On-site Calibrator for Voltage Transformers




The on-site calibrator for voltage transformers features a large-screen Chinese character LCD display and employs backlight control for the LCD, allowing users to conveniently adjust the backlight according to ambient light, thoroughly solving the problem of digital tubes being hard to read outdoors. It directly provides test values and rounded values for each point, with immediate prompts for out-of-tolerance conditions. It offers standard test methods for S-class and light-load conditions, along with corresponding automatic control functions for the operating console. It provides asset number entry and storage functions, facilitating on-site data management by computer. It directly displays the on-site CT test wiring diagram.

Introduction



Automatic Measurement


According to the measurement points required by regulations, it can automatically perform full load and light load measurements with different accuracy requirements.

Automatic Storage




It can store 50 groups (full load and light load) of measurement data.

Automatic Rounding




It can automatically round error data according to the accuracy class of the tested transformer and determine whether it is out of tolerance.

Computer Connection


It can transfer data to the "HHH-H Transformer Error Data Management System" (software) for computer management.

Calibration Bench Connection




It connects with the HEJH-H transformer calibration bench to achieve full automation.

Direct S-class Measurement




It can directly measure S-class transformers with a wide measurement range.
