AC Resonant test system with partial discharge is used to make the ac resonant test for the GIL, GIS, busbar,cable, transformer and other electrical materials. For such equipment, we also can control its partial discharge into one very lower value .It is widely used at site based on its lighter weight, portable installation and easier operation. Variable Frequency is from 20Hz~300hZ.
It’s used to make partial discharge induced voltage test for power transformer, and AC withstand voltage test for power cables, GIS, etc
This product adopts digital frequency conversion technology, single-chip microcomputer control, and the step-up, step-down, measurement and protection are fully automated. Due to full electronization, it has small volume and light weight. It adopts large screen color touch screen, which is clear and intuitive, simple to operate and display output waveform. The design index conforms to the national standard of general technical conditions for special test instruments for power equipment, Part 4: General technical conditions for ultra-low frequency and high voltage generators, which is simple and convenient to use.
HMGTU series partial discharge high voltage test system is suitable for high voltage test, big capacity GIS power equipment insulated withstand voltage test, partial discharge test and GIS transformer accuracy test.It can complete partial discharge test under normal circumstances, the general background discharge can be less than 5Pc.
Power frequency discharge free HV test set is used for or partial discharge and power frequency withstand test , checking the insulation level of power-frequency voltage for all kinds of insulation materials and electric products, which is widely used in electric products manufactures, electric power operation departments, scientific research institutions, colleges & universities.It is a necessary equipment for all walks of high voltage testing.
Multistage impulse generator is a test equipment to simulate the high voltage of pulse. In real life, pulse high voltage is often encountered. For example, in nature, lightning strikes, the lightning will appear very high pulse current and voltage, the surrounding will also sense a very high pulse voltage, and in the power system, the switching equipment in the joint operation will also lead to transient pulse voltage. These transient pulse voltage amplitudes are often in the tens of thousands of kV or more, which will cause equipment damage and endanger personal safety, so it is necessary to conduct test studies on shock voltage. On the other hand, it is very meaningful to simulate the natural lightning phenomenon to carry out the study of discharge mechanism.
High Voltage Impulse Generator High Voltage Impulse Generator is used to make standard lightning impulse voltage full-wave, interception, steep wave and other impulse voltage tests for GIS combination electrical appliances, air gaps, insulator strings, bushings, etc .
