Principle of Operation of the Leakage Tracer Tester
The operation principle of a leakage tracer tester primarily involves insulation quality testing and leakage current testing of electrical equipment:
Insulation Quality Testing:
In insulation quality testing, the leakage tracer tester applies a specific voltage (often several times the rated operating voltage) to the insulation structure of the device under test. It then detects the leakage current on the insulation structure to assess the device’s insulation quality. Effective insulation quality prevents current leakage, ensuring device safety and reliability.
Leakage Current Testing:
During leakage current testing, the leakage tracer tester applies a certain fault current to the device under test and measures the leakage current while conducting analysis. By measuring and analyzing leakage current, the tester evaluates the device’s safety performance under fault conditions.
Components of the Leakage Tracer Tester and Their Functions
The leakage tracer tester is a vital equipment widely used in the electrical equipment and engineering fields, primarily for testing insulation quality and electrical safety performance. Its main components include the power module, measurement module, display module, and control module. Here’s a detailed introduction to each part:
