Overview

The fully functional transformer characteristic comprehensive tester is used for automatic testing of protective and metering CT/PT, suitable for laboratory and on-site testing. If it is not in a laboratory environment, the tester must be reliably grounded before it can be used. The selection of grounding point should be as close as possible to the test object, and during testing, always keep one terminal on the high-voltage side of the transformer grounded.

Product Overview

Comprehensive tester for the characteristics of full function transformersUsed for protection and measurement purposesCT/PT performs automatic testing, suitable for both laboratory and on-site testing. If it is not in a laboratory environment, the tester must be reliably grounded before it can be used. The selection of grounding point should be as close as possible to the test object，During testing, always keep one terminal on the high-voltage side of the transformer grounded.When measuring the transformation ratio of a transformer, please ensure that the wiring is correct, otherwise life-threatening voltage may be generated inside the transformer and the connected transformer may be damaged by the tester.
