The KDZD4500 Handheld Transformer Turns Ratio Tester is an essential tool for electrical power system maintenance, specifically designed for on-site inspection of Current Transformers (CT) and Voltage Transformers (VT). It addresses the challenges of traditional current-method testing, which is often impractical for high-capacity systems requiring primary currents of thousands or tens of thousands of amperes. Utilizing an advanced voltage measurement method, this device enables technicians to perform accurate ratio and polarity tests on-site without the need for bulky heavy-current generators. It is ideal for routine maintenance in substations, power plants, and industrial facilities, ensuring the accuracy and reliability of protective relaying and metering systems.
