Relationship with Other Instruments: Positioning of Insulation Resistance Tester in the Test Flow
Relationship with Other Instruments (Positioning in the Test Flow) Based on your previous questions, the position of the insulation resistance tester in the test chain is as follows: Step 1: Insulation Resistance Test (This Instrument) Purpose: Quick screening. If the insulation resistance is extremely low (e.g., close to 0), it indicates a serious short circuit or grounding fault. Decision: Only after the insulation resistance passes can subsequent dielectric loss testing and withstand voltage testing be performed.
