Description
Overview
GAOTek low voltage current transformer ratio tester transformation ratio tester can be widely used in 380 V- or 220-volt power systems. It can easily and quickly realize on-line detection of current transformers in metering devices and current and leakage in 380 V- or 220-volt power systems. The measurement of the current value realizes that the transformation ratio, phase and polarity of the current transformer in actual operation can be accurately tested without power failure. The tester is composed of a host, a primary flexible current clamp, and a secondary current clamp. The diameter of the flexible current clamp is 0.315 in (8 mm). It is especially suitable for testing places in small spaces and densely arranged cables. It provides a safe, accurate and convenient way for electricity inspectors. The application of new power equipment will bring significant economic and social benefits to power companies in power management.
