Product description
Product parameters
Reference standards: JJG314-2010, JJG313-2010.
Features:
● Real virtual instrument design, fully automatic control, just operate the mouse and keyboard through the virtual instrument interface on the computer screen, input the transformer type, range, accuracy level, capacity, power factor and other parameters, then complete the measurement To the entire process of printing a certificate;
● Power supply by variable frequency source, fast, stable and accurate fixed point, completely solve the 1% fixed point problem of S-class transformer;
● Voltage and current load box gear program control automatically switches, no manual calculation and manual shifting;
● It has perfect alarm and overcurrent protection function, and can also be used as a power frequency withstand test bench for transformer withstand voltage test.
