Product Features
- The main unit features an H-type, 6-stage tower-style modular design with symmetrical charging on both sides, ensuring easy disassembly and maintenance as well as structural stability;
- Thyristor-controlled constant-current voltage regulation with continuously adjustable charging voltage; the charging power automatically shuts off at the moment of ignition;
- The spark gap motor provides electric distance adjustment, supporting manual/automatic adjustment with upper and lower limit protection; the first stage features opposite-polarity triggering, while stages 2–6 use three-gap ignition, with a synchronous failure rate of <2%;
- The leading-edge and trailing-edge resistors are inductively wound with interchangeable board configurations, include built-in storage positions, and support flexible multi-stage parallel and series combinations;
- Fully automated control via a complete Siemens PLC system; data acquisition via an industrial PC and Tektronix oscilloscope; automatic waveform analysis, data storage, and report printing;
- Expandable equipment mounting brackets and charging units; comprehensive protection features including overvoltage, overcurrent, automatic grounding, and emergency shutdown.

FAQs
Q: Can the equipment perform tests continuously for extended periods?
A: It can operate continuously at a rate of one charge-discharge cycle every 120 seconds at 80% or more of the rated voltage; at less than 80%, it can operate continuously for extended periods.Yes. Fiber-optic communication is used between the industrial control computer and the PLC control cabinet, allowing remote operation of the isolation and grounding switches on the GTU-250/500 unit from the control room in the 1000 kV test hall.
Q: What are the configurations for the wavefront and wave-tail resistors? Are they compatible with cable testing?Does the system support remote control?
A: The standard configuration includes 3 sets of lightning wavefront resistors, 2 sets of wave-tail resistors, and 1 set of operation wave-tail resistors. Dedicated resistors can be added to support 0.4μF and 1μF power cable impulse tests.
Q: What is the charging method?
A: A bilateral symmetrical constant-current charging method is used, with thyristor-controlled constant-current voltage regulation, continuously adjustable from zero to the set voltage. The charging power supply automatically shuts off at the moment of ignition and discharge.
