Short Description
The UT225B Wireless High & Low Voltage Transformer Turns Ratio Tester is intended for rapid, on-site testing of current transformers in metering installations.
It monitors primary current, secondary current, and transformer turns ratio while also determining phase type and polarity.
The UT225B can perform online measurements on systems up to 35 kV and uses wireless transmission between the primary current clamp and the main tester, making it ideal for use in substations, power plants, industrial facilities, electrical inspection, and maintenance.
