a portable instrument for measuring illumination; a type of photometer. The simplest luxmeter consists of a selenium photocell that converts luminous energy into the energy of an electric current, which is measured by a pointer-type microammeter with scales calibrated in luxes (Ix). Different scales correspond to different ranges of the illumination being measured; scale changes are made by a switch that changes the resistance in the electric circuit. For example, a Iu-16 luxmeter has three measuring ranges: up to 25, up to 100, and up to 500 I ....etc

The Trivector meter is a measuring instrument which measures the kW, kVAr, the kVA of a power line. These instruments can measure both power as well as energy. Trivector meters are normally used in substations and to measure the power flowing through the feeders. They are used for billing power drawn by industrial customers. The Trivector enables the simultaneous measurement of different electrical parameters which enables accurate assessment of the power consumed.

Trivector is called so as it measures three vectors representing the ac ....etc

An electricity meter, electric meter, electrical meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device.Electric utilities use electric meters installed at customers' premises to measure electric energy delivered to their customers for billing purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour . They are usually read once each billing period.When energy savings during certain periods are desired, ....etc

Energy meters are the basic part to measure the power consumption. It is used everywhere, no matter how big or small consumption it is. It is also known as watt-hour meter. Here we discuss the construction and working principle of induction type energy meter.To understand the structure of watt-hour meter, we must understand the four essential components of the meter. These components are as follows:

Driving system

Moving system

Braking system

Registering system

Driving System

The components of this system are two silicon steel ....etc

CEILING FAN OBJECTIVE : To study the working, construction And troubleshooting of Ceiling Fan
2. INTRODUCTION A ceiling fan is a device suspended from the ceiling of a room, which employs hub- mounted rotating paddles to circulate air. First electrically powered fan was invented in 1882 by Philip Diehl. Crompton Greaves Ltd is the leading manufacturer of fans.
3. PRINCIPLE If a current carrying conductor is placed in a magnetic field it experience a force and start to rotate. The direction of rotation can be found by Fleming s Left Hand R ....etc

FULL ANSWER
Megger testing does not cause any damage, making it a good option when someone does not want to put holes in walls to test electrical insulation for any problems or issues. The testing device only goes between 500 and 1,000 volts, which is relatively low. Due to the low voltage, some punctures in insulation go undetected. It generally provides information about the leakage current and whether insulation areas have excessive dirt or moisture as well as the amount of moisture, deterioration and winding faults. ....etc
