Contact Resistance Tester
-
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.

AC Rectifier Type Coil Meter
-
measures the alternating voltage and current with the help of rectifying elements and permanent magnet moving coil type of instruments. However the primary function of rectifier type of instruments work as voltmeter. Now one question must arises in our mind why we use rectifier type of instruments widely in the industrial world though we have various other AC voltmeter like electrodynamometer type instruments, thermocouple type instruments etc? The answer to this question is very simple and is written as follows.
