Induction tester purpose
WebThe terminals of an induction motor are marked as A1, A2; B1, B2; C1, C2. If their polarities are unknown, you need to locate them out by testing each terminal. You can test the terminals by using DC and AC supply separately. Testing by AC Supply. By using a multimeter, determine the continuity between random sets. Web16 aug. 2014 · The test values should be normalized to 20°C for comparison purposes. Insulation resistance test is conducted in most of the substation equipment is high and medium voltage substations. The general rule of thumb that is used for acceptable values for safe energization is 1 MΩ per 1000 V of applied test voltage plus 1 MΩ.
