This instrument integrates multiple test functions into one unit, capable of comprehensively testing the excitation characteristics, ratio, polarity, and other parameters of instrument transformers. V-A Characteristic (Excitation Characteristic) Test: This is the core function. The instrument automatically boosts voltage or current, measures and plots the V-A characteristic curve of the transformer, and automatically calculates the knee point voltage/current values. This curve is the foundation for evaluating transformer saturation characteristics and performing relay protection calculations.

Instrument Transformer Characteristic Tester, Also Called Instrument Transformer Comprehensive Tester or V-A Characteristic Tester

The Instrument Transformer Characteristic Tester, also called Instrument Transformer Comprehensive Tester or V-A Characteristic Tester, is a specialized device for testing key performance parameters of Current Transformers (CT) and Voltage Transformers (PT). It plays a vital role in the installation, commissioning, and maintenance of power systems, ensuring that instrument transformers can accurately transmit signals and guaranteeing the correct operation of relay protection and metering devices.
