Product Description

Product Introduction:

The Multifunctional Comprehensive Transformer Tester is designed for automatic testing of protective and metering CT/PT, suitable for both laboratory and on-site testing. The device uses a single-phase 220V power supply, with fully isolated output, multiple protections, safe and reliable. No external auxiliary equipment is needed; all testing items can be completed with the standalone unit. Equipped with an intelligent rotary controller, it is easy to operate, features a large LCD screen, and comes with a built-in micro fast printer for direct on-site printing of test data. The Multifunctional Comprehensive Transformer Tester can automatically provide CT/PT (excitation) knee-point values according to regulations, and automatically generate 5% and 10% error curves. The tester has a built-in large-capacity memory that can store up to 3000 sets of test data, which is never lost after power-off. It is configured with a USB communication interface and supports U-disk data transfer. It is compact and lightweight, making it very suitable for field testing.
