Module type AC Test Transformer Systems
(for Transformer Applied Voltage Test)

Module type AC Test Transformer Systems

YDTW series AC test transformers are of module type and oil insulated, inner insulating materials are transformer oil, shells are insulating cylinders, which are made of epoxy resin.

TThe high voltage can directly feed to test object without bushing, and modules are allowed to stack in cascade to reach very high voltage levels by keeping reasonable floor space.

Rated voltage of single module can be up to 750kV, the highest voltage can reach 2250kV by stacking three of these transformer modules.

AC Resonant Test Systems with Variable Inductance
(for Transformer Applied Voltage Test)
AC Resonant Test System with Variable Inductance

IRST series variable inductance resonant test systems are designed to compensate capacitance in testing circuit precisely by adjusting inductance of HV reactors, when test system gets in resonance, it outputs continuous AC voltage of power frequency (mainly 50 or 60Hz, matches feed-in mains).

IRST series HV reactors, main part of the system, work on fixed frequency and variable inductance, are of oil insulation and epoxy glass-fiber insulating shell, module type and stackable, voltage up to 2000kV.

These systems offer significant advantages to standard AC test systems where the load is largely capacitive.
