A ceiling fan is a mechanical fan, usually electrically powered, suspended from the ceiling of a room, that uses hub-mounted rotating paddles to circulate air.

Casablanca Fan Co. Zephyr ceiling fan from the early 1980s.
A ceiling fan rotates much more slowly than an electric desk fan; it cools people effectively by introducing slow movement into the otherwise still, hot air of a room. Fans never actually cool air, unlike air-conditioning equipment, but use significantly less power (cooling air is thermodynamically expensive). Conversely, ....etc

Ballistic galvanometer

A ballistic galvanometer is a type of sensitive galvanometer, commonly a mirror galvanometer. Unlike a current-measuring galvanometer, the moving part has a large moment of inertia, thus giving it a long oscillation period. It is really an integrator measuring the quantity of charge discharged through it. It can be either of the moving coil or moving magnet type.

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

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

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

The megger is a portable instrument used to measure insulation resistance. The megger consists of a DC generator and a direct reading ohm meter.
The megger measures the insulation resistance between the body of a machine and the armature winding. By applying the operating voltage between the body of machine and the armature winding one can check the insulation resistance. If the reading of the megger is less than 1 Mohm it indicates that there is some fault.
The megger checks the the possible following faults:

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
