Types of Electrical Testing Equipment Instruments Uses and Its Definition

Meter Testing Instrument in the field of electrical engineering or in electronics engineering is so importantwithout those instrument you cannot repair or analyze the system or equipmnent or even design a new one. As I googling  on the Net I discovered that huge of instrument testing for as to know as an electrical engineer. Like Cable-Length Meters, Electric Tachometer, Electrical Thermometers, Footcandle Meter, Frequency Meter, Miscellaneous Testing Instruments and many others.

Cable-Length Meters
Cable-length meters measure the length and condition of a cable by sending a signal down the cable and
then reading the signal that is reflected back. These instruments are also called time-domain reflectometers
TDRs. A similar instrument used to measure the length of fiber optic cables is called an optical timedomain
reflectometer ODTR.

Electric Tachometer
This consists of a small generator that is belted or geared to the equipment whose speed is to be measured.
The voltage produced in the generator varies directly with the rotational speed of the generator.
Since this speed is directly proportional to the speed of the machine under test, the amount of the generated
voltage is a measure of the speed.

Electrical Thermometers
For the measurement of temperatures, there are three basic types of electrical thermometers.Resistance thermometers operate on the principle that the resistance of a metal varies in direct proportion to its temperature. They are normally used for temperatures up to approximately 1500°F.Thermocouples operate on the principle that a difference in temperature in different metals generates a voltage, and are used for measuring temperatures up to about 3000°F. Radiation pyrometers and optical pyrometers are generally used for temperatures above 3000°F. They combine the principle of the thermocouple with the effect of radiation of heat and light.

Footcandle Meter
A footcandle meter consists of a photosensitive element and a meter that indicates the average illumination of a room or other space in footcandles. Typical footcandle meters can read light intensity from 1 to
500 footcandles or more. To use the footcandle meter, first remove the cover. Hold the meter in a position so the cell is facing toward the light source and at the level of the work plane where the illumination is required. The shadow of your body should not be allowed to fall on the cell during tests. A number of such tests at various points in a room or area will give the average illumination level in footcandles. Readings are taken directly from the meter scale.

Frequency Meter
Frequency is the number of cycles completed each second by a given AC voltage, usually expressed in
hertz ; 1 Hz = 1 cycle per second. The frequency meter is used with AC powerproducing devices like generators to ensure that the correct frequency is being produced. Failure to produce  the correct frequency can result in overheating and component damage.

Miscellaneous Testing Instruments
Ammeters, voltmeters, and megohmmeters are the most common analog devices used for field testing
and troubleshooting applications. However, several other specialized types of test instruments should be mentioned briefly.

Power Factor Meter
Power factor is the ratio of the true power,voltamperes to apparent power,watts, and it depends on the phase difference between current and voltage. Three-phase power factor meters are installed in
switchboards. Many utilities charge large commercial and industrial users a penalty if power factor falls
below 90 percent; so these users try to maintain high power factor at all times. A high power factor provides better voltage regulation and stability.

Power Quality Analyzers
Power quality analyzers are portable test instruments similar in construction to the digital multimeters.
unlike DMMs, which typically measure only one property of electrical circuits at a time, power quality analyzers have dual probes that allow both voltage and current to be measured simultaneously. Power quality analyzers can also measure frequency and harmonics. The ability to measure Power quality analyzer display showing voltage on top, current on bottom, and time stamp at upper right. and display multiple circuit characteristics at the same time is useful in troubleshooting power quality problems in power distribution systems.

Photo Tachometer
This instrument aims a light at the rotating shaft on which there is a contrasting color such as a mark, a chalk line, or a light-reflective strip or tape. The rotational speed in rpm is read from an indicating scale. Photo tachometers are especially useful on relatively inaccessible rotational equipment such as motors,
fans, grinding wheels, and other similar machines where it is difficult, if not impossible, to make contact
with the rotational unit.

Phase-Sequence Indicator
A common phase-sequence indicator is designed for use in conjunction with any multimeter that can
measure AC voltage. Most can be used on circuits with line voltages up to 550 VAC, provided the instrument used with the indicator has a rating this high. To use the phase-sequence indicator, set the multimeter to the proper voltage range. This can be determined if it is not known by measuring the line voltage before connecting the phase-sequence indicator. Next, connect the two black leads of the indicator
to the voltage test leads of the meter. Connect the red, yellow, and black adapter leads to the circuit in
any order and check the meter for a voltage reading. If the meter reading is higher than the original circuit voltage measured, then the phase sequence is black-yellow-red. If the meter reading is lower than the original circuit voltage measured, then the phase sequence is red-yellow-black. If the reading is the
same as the first reading, then one phase is open.

Tachometers
A tachometer is a device that indicates or records the speed of rotating equipment (motors and generators) in revolutions per minute,rpm. There are several different types:

Vibrating-reed Tachometer
This instrument is simply held against the motor, turbine, pump, compressor, or other rotating equipment, and the speed is shown by the vibration of a steel reed, which is tuned to a certain standard
speed.

Electrical Illumination Tutorials and Its Engineering Definition

Light 

The light is defined as the energy radiated in the form of waves which produces the sensation of vision to the eyes. It may be natural light from sun or the artificial from the means created by human beings.

Lumen

It is the unit of luminous flux and is defined as the luminous flux emitted per unit solid angle by a point source of one candle power.

Brightness 

The brightness is defined as the luminous intensity per unit projected area of either a source of light or reflecting surface. It is denoted by B and the unit is stib which is nothing but candle per centimeter squared, other unit is nit which is candle per meter squared.

Coefficient of Utilization

It is defined as the ratio of the lumens  actually received by a particular surface to the total lumens emitted by the luminous source. The coefficient of utilization or the utilizing factor is the total lumens actually received by the working plane per total lumens emitted by the light source.

Candle Power 

The candle power is the light radiating capacity of a source in a given direction. It is defined as the number of lumens given out by a source in a unit C.P. and one meter away from it.

Colour

The sensation of colour is due to the difference in the wavelengths of the light radiations. Visible light can have length between 4000 A to 7500 A and colour varies in the way.

Luminous Intensity

The luminous intensity in any given direction is the luminous flux emitted by a source per unit solid angle. It is represented by I and measured in candle power.

Luminous Flux 

It is the total quantity of light emitted by the source of light per second. It is represented by symbol O or F. It is measured in lumen. The total flux emitted by a source of I candle is 4 pi times I lumen where I is the luminous intensity of the source.

Some Characteristics of a good Illumination

1. The light source should not strike the eyes of the worker.
2. The type and size of the lamp should be correct.
3. Location should be proper.
4. Reflecting equipment should be suitable.

The Advantages of Correct Illumination

1. Factory production increases
2. Accidents decrease
3. Wastage of jobs decreases.

The sources of light is Three practicable ways of producing light are incandescent of heated filament  and electric are glow discharge.   Where the incandescent filament lamp is the light obtained by passing, current through a high resistance called the filament, this current being sufficient to raise the filament to luminosity. The filament is enclosed in an evacuated glass bulb. The object of the vacuum is first to prevent the filament burning away to reduce loss of heat by convection. The filament must be a conductor and must be capable of withstand a hight temperature.

All About Electrical Relays, Principles, Classification and Requirements

Protective relays
Relay is a device by means of which an electric circuit can be controlled by the change in the same circuit or in other circuit. The primary function of the protective relay is to sense the fault in the system, compare the signal so obtained with  the reference signal under normal conditions of operation and amplify the error signal such that the trip coil of the circuit breaker is energized and faulty section of the system is disconnected from the rest of the system.Under normal conditions of the system, a protective relay is required to keep itself alert such that in case of any emergency, the action may  be taken almost instantneously.It should remain silent under normal condition. Under certain operating condition, the power system components are required to carry more than rated current on a temporary basis. During peak load condition, the power system components arc intentionally over-loaded. Under such conditions of operation, often known as abnormal condition, it is not necessary to disconnect the section from the system. When the operation parameters are unduly strained, the protective relays are required to energize the alarms such that proper precautions are taken.

The Basic Principles of Relays
In electromechanical relays, there are one or more coils, movable elements, contact system, etc. The operation of such relays depends on whether the operating torque/force is greater than the restraining torque/force.The relay operates, if the net force, F in equation given below is positive. Where F is the net force, Fo is the operating force and Fr is the restraining force. In other words, the relay operates only if the operating force is greater than the restraining force. In electromechanical relays, the operating torque is produced by electromagnetic attraction/electromagnetic induction/thermal effects of electric current. The restraining torque is given by springs.

The Classification of Relays
Protective relays are classified as follows according to their construction and the principle of operation.
1. Electromagnetic relays These are actuated by Direct current or Alternating current quantities.
2. Electomagnetic induction relays
3. Electothermal relays
4. Static relays these employ transistors or magnetic amplifiers to obtain the operating characteristic.
5. Electrodynamic relays these are operate on the same principle as moving coil instruments.
6. Under-voltage, under-current and under-power relays.
7. Over-voltage, over-current and over-power relays
8. Direntional or reverse current relays
9. Differential relays
10. Distance relays

The Basic Requirements of Protective System
The efficient protective relaying system should posses the following characteristics:
1. Speed 
Minimum voltage and minimum fault time operate.
2. Selectivity
Maximum continuity of service by disconnecting the faulty part of the system.
3. Sensitivity
Capability of operating reliably under the actual desired conditions.

Protective Relays
These are the devices that detect abnormal conditions in electrical circuits by measuring the electrical quantities which are different under normal and faulty conditions. Due to abnormal conditions, voltage, current, phase and frequency may change. After detecting the fault, the relay operates to complete the trip circuit which results in the opening of the circuit breaker and isolating the faulty circuit.

It is a common practice in industry to employ A.C. motors whenever they are inherently suitable or can be given appropriate characteristics by means of power electronics devices.


Basic Electrical Measurements
Voltmeters read across the circuit or load under test. This means that typical readings are taken with the

Extraordinary Electrical Conductivity
This is understandable, given their high electrical conductivity, and the incredible sharpness of their tip (because the smaller the tip’s radius of curvature, the more concentrated will be an electric field, leading to increased field emission; this is the same reason lightning rods are sharp). The sharpness of the tip also means that they emit at especially low voltage, an important fact for building low-power electrical devices that utilize this feature.

All about electronic microchip How it works?

What is microchip and how does it works? is most frequent question in tackling about electronics and  electrical world. According to some site A microchip is a small semiconductor used to relay information through specific electrical characteristics. Other says is a unit of packaged computer circuitry usually called an integrated circuit that is manufactured from a materials such as silicon at a very small scale. Also electronic equipment consisting of a small crystal of a silicon semicoductor fabricated to carry out a number of electronics fucntion in an integrated circuit whatever it is we know that microchip is written in the bilble though did write word for word but if you meditate the word deeply you will find that it is true like in Revelation 13:7 says And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindred and tongues, and nations. After the second coming of Jesus Christ The Anti-Christ will come in and rule the whole earth, and all governments, king prime and ministers including presidents will submit to his power. To truly deeply understand please see useful links for further understanding about this fact MicroChip or a Biochip called 666 or the mark of the beast.




Is the biochip the Mark of the Beast?
What is The Biochip Technology?, What is a biochip implant?, Computer Microchip, Antenna Coil, Tuning Capacitor, Glass Capsule, How it works, Common Misconceptions About Biochip implants, One major concern with a implanted biochip is theft. Is the Biochip the Mark of the Beast?,


The Mark of the Beast
The technology exists today, and people are getting chips implanted under their skin today.
We have the social security number today, we have paper money today.Here are more scriptures in Revelation that talk about the mark of the beast. 


666 and the New King James Bible
This is one sign that we are going to a cashless society. By swiping your card and punching your number, the whole transaction is made. Also popping up everywhere are machines in stores to do your banking at. Amazingly, 10 to 15 banks, credit unions.


MARKTECH
The mark will be implanted under the forehead, so people who have no right hand could also have the mark. The microchip assembly, called radio frequency identification (RFID) is already used in animals.
