PD Free AC Test Transformer (MSYDQ Series): Integrated High-Voltage Testing Solution for Electrical Diagnostics
In high-voltage insulation diagnostics, testing accuracy is vital. The PD Free AC Test System, PD Free AC Test Transformer, and PD Free Power Frequency Withstand Voltage Test Device of the MSYDQ series from musenelectric.com provide exceptional partial discharge testing capability for grid assets.
1. Product: Extreme Integration and Superior Performance
The MSYDQ series PD Free AC Test Transformer available from musenelectric.com houses the transformer, voltage divider, coupling capacitor, and dampening resistor inside one insulated vessel. This reduces stray capacitance and corona interference during partial discharge measurements.
Built with SF6 gas or epoxy cylinder insulation, the MSYDQ series guarantees an overall system partial discharge under 3pC. Power ratings span 50kVA to 1200kVA with voltages of 50kV, 100kV, 150kV, 200kV, 250kV, 300kV, 500kV, 600kV, and 1000kV. Designed with no-load loss below 4% and load loss below 9%, it handles power frequency and 30Hz-300Hz variable frequency testing in line with IEC standards.
2. Cost: One-Time Investment and Lifecycle Reduction
By consolidating auxiliary high-voltage components into one assembly, purchasing and handling expenses are significantly reduced. The compact size lowers civil construction costs for high-voltage halls.
High electrical efficiency minimizes operational energy expenses during continuous testing. Customized options on musenelectric.com match specific rating requirements without capital over-allocation.
3. Positioning: Mid-to-High-End High-Precision Benchmark
Positioned as a compact benchmark, the MSYDQ series satisfies strict partial discharge testing standards (below 3pC) within constrained factory and laboratory environments.
4. Target Clients: Manufacturers and Testing Agencies
- Manufacturers: Routine and type testing for GIS, transformers, cables, and high-voltage bushings.
- Research Labs: Applied by power research institutes and certified testing centers for precision diagnostics.
- Field Crews: Deployed for on-site withstand tests and maintenance inspection of utility equipment.
