Experienced electricians know that DC resistance tests are crucial for transformers after factory testing, installation, overhauls, or tap switch changes. DC resistance testers are commonly used.

With the continuous development of society, the capacity of power equipment is getting larger and larger, so the performance requirements for its insulation part are higher. Some traditional conventional megohmmeters can no longer complete high-requirement insulation tests. Nowadays, the insulation resistance tester is more commonly used. So what should we pay attention to when using this instrument? Let me explain it to you below.

The power test regulations require a series of insulation performance tests for numerous power equipment such as cables, motors, generators, transformers, mutual inductors, high-voltage switches, lightning arresters, etc. The first step is to perform insulation resistance tests using an intelligent insulation resistance tester.
