Introduction
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.

Application
AC resonant test systems are mainly used to output AC voltage for high voltage routine, type and development testing of capacitive test objects. These systems exert the principle of series resonance, as per f=1/2LC, the connection of HV reactors (inductance L) to a capacitive loads (capacitance C) form an oscillating circuit with the frequency (f) of power supply.
Compared to conventional AC test transformers, the relatively lower power required (1/Q), smaller dimension and lighter weight favor these systems as the most practical for field testing, and large capacitance loads.
