Question

Write specifications of insulation tester used in this experiment

Answer 1

The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. ... The Megger insulation tester is essentially a high-range resistance meter (ohmmeter) with a built-in direct-current generator.

Answer 2

Answer :

A compact, movable device called the insulation tester provides a direct reading of resistance in ohms or megohms.

The insulation tester is basically an ohmmeter with a erected- in direct-current creator for measuring high- range resistance.

Explanation:

• A unique kind of ohmmeter called a megohmmeter, also known as an insulation resistance tester, is used to gauge insulators' electrical resistance.
• When the insulation in electrical devices, parts, and equipment used in industrial plants, buildings, and other settings deteriorates over time of use, hazards such as electric shock and short-circuits are caused.
• Portable insulation resistance testers are designed to help prevent these hazards.
• Place the positive probe on the ground wire or the grounded metal junction box while evaluating the insulation's resistance to ground, and the negative probe on the conductor or terminal.
• Give the Megger a minute of energy. At the conclusion of the minute test, read the resistance value and record it in your table.
