Generators & Motors

In order to check and verify that system and component meet the specified requirements, all kinds of generators and motors need be tested in many items. We offer AC and impulse dielectric test system for insulation performance test.


Cylinder Module type AC Resonant Test Systems with Variable Inductance
Variable Inductance AC Resonant Test Systems

IRST series AC resonant test systems use cylinder module type variable inductance HV reactors, which are of oil insulation and epoxy glass-fiber insulating shell, stackable module type allows higher output voltage, up to 2000kV.

These systems vary the reactor inductance to create resonant circuit with load capacitance in power frequency, when get in resonance, they output continuous AC voltage of power frequency (mainly 50 or 60Hz, matches feed-in mains) for testing.

Variable Frequency Resonant Test Systems

FRST series AC resonant test system use cylinder module type HV reactors with fixed inductance, which are of oil insulation and epoxy glass-fiber insulating shell, these reactors can be used in parallel for higher current, or in series for higher voltage (up to 2400kV).

These systems vary the frequency of power supply to create resonant circuit with load capacitance and fixed inductance of reactors, then output pure sine wave AC voltage for testing, typical test frequency range is 20~300Hz.

Cylinder Module type Power Frequency AC Test Transformer Systems
Cylinder type AC Test Transformer

YDT series cylinder type 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.

The 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.
