Products Description
This unit is a GTU fully enclosed 1200kVA/600kV test system, specifically designed for factory testing of GIS (gas-insulated switchgear) with voltage ratings of 252kV and below. The system features a fully enclosed design with no special requirements regarding altitude or humidity, enabling power-frequency withstand voltage tests and partial discharge detection to be conducted indoors in a non-shielded environment. All tests can be completed with a single connection to the test specimen via a dedicated interface, significantly improving testing efficiency.

Products Features
- Fully Enclosed Design: Not limited by altitude or humidity, it adapts to complex indoor environments and offers high safety.
- Extremely Low Partial Discharge Levels: The system's partial discharge is ≤2 pC at rated voltage and ≤1 pC at 80% of rated voltage, meeting the requirements for high-precision partial discharge detection.
- Integrated Quick Connection: Connects to the test specimen in a single step via a dedicated interface, eliminating the need for repeated wiring and significantly improving test efficiency.
- Precise Compensation Adjustment: The compensation reactor employs a combination of "continuously adjustable + fixed compensation" with motorized switching, ensuring high compensation accuracy (±20 kvar).
- Intelligent Control System:
- Centralized control of voltage step-up/step-down, compensation adjustment, and circuit breaker operation;
- Real-time display of input/output current and voltage, compensation current, high-voltage values, and circuit breaker status;
- Equipped with multiple protections against overcurrent, overvoltage, and flashover, along with audible and visual alarms at the start of testing.
- High-Quality Partial Discharge Tester: 4-channel input, supporting multiple display modes such as sine wave, elliptical, horizontal, 2D, and 3D, with the ability to record and print results.
- Strict Factory Acceptance Standards: Covers 11 inspection items, including appearance, sealing, withstand voltage, partial discharge, waveform distortion, and measurement accuracy, to ensure the system meets performance standards.
- Flexible Transportation and On-Site Assembly: Small components are shipped pre-assembled, while large components are disassembled and then assembled and commissioned on-site by the manufacturer's technical staff to ensure delivery quality.
- Short Production Cycle: Production can be completed within 45 working days after the technical agreement and contract take effect.
