FAQs

Q1: What is a insulation tester?
A1:
Insulation tester, also known as megohmmeter or meggers, are widely used to measure cables for generators, motors, power transformers, wiring, appliances and other electrical installations such as control, signal, communication and power ) insulation resistance. They are often used in routine maintenance procedures to indicate changes in the insulation resistance of a motor over months or years. Large changes in insulation resistance may indicate potential failures. Therefore, regular calibration of the megohmmeter is required to ensure that the meter itself has not changed over time.

Q2: What is insulation resistance?
A2: Insulation resistance is the DC resistance of the insulation under the specified conditions, that is, the DC voltage is applied to the dielectric, after a certain period of polarization, the resistance corresponding to the leakage current flowing through the dielectric is called insulation resistance. It is the most basic insulation index of electrical equipment and electrical circuit.

Q3: How to measure insulation resistance?
A3: 1. Connect all the lines according to the method measured by the insulation resistance tester. The connection between the measuring lead and the pipe is more suitable for the use of magnetic joints or clips, and the connection point must be free of rust.
2. The measuring instrument should be a 500V/500MΩ (the error here cannot be greater than 10%) insulation tester. Turn the handle of the megohmmeter to reach the specified speed for 10 seconds. The resistance value indicated by the megohmmeter stably is the insulation resistance value of the insulating joint (flange), which is required to be greater than 10 megohms.

Tips: How to choose a digital megger insulation tester?

The digital megger insulation tester has powerful functions and can cope with various complex situations on site, such as effectively eliminating interference, automatically tracking the most suitable test conditions, etc. Some digital meggers can also directly measure interference frequency and interference voltage. If you need an insulation tester with higher test accuracy, you can use a double clamp-on grounding resistance tester. For example, the grounding resistance measurement of grounding devices such as output pole towers, microwave towers, lightning rods and auxiliary devices (faucets, water pipe devices) with good grounding conditions, can use clamp-on type grounding resistance meter to measure the grounding resistance. For large-scale system grounding, network grounding, and soil resistivity tests, it is better to choose a ground resistance tester.
