Products Description
HMGTU Fully Enclosed 1200 kVA/1200 kV Test System
Primary Application: Specifically designed for insulation withstand voltage tests, partial discharge tests, and GIS transformer accuracy tests on ultra-high-voltage GIS and GIL power equipment rated at 500 kV and above.
Target Customers: Primarily intended for GIS/GIL equipment manufacturers, ultra-high-voltage substations, and manufacturers of bowl-type insulators and insulating structural components, for use in factory acceptance tests, preventive maintenance tests, and on-site acceptance tests.
Products parameters
- Rated Capacity: 1200 kVA
- Rated Output Voltage: 0–1200 kV
- Partial Discharge Level: ≤ 3 pC (at rated voltage), exceeding the requirements of the IEC 60270 standard
- High-Voltage Generation Method: Can utilize either direct step-up via a high-voltage transformer or series resonance (power-frequency/variable-frequency) methods; both employ single-stage step-up without the need for cascaded stages
- Partial Discharge Suppression: The high voltage is fully sealed within a shielded enclosure, and the total partial discharge level can be controlled within 5 pC
