Why Pre-Delivery Switchgear Testing Matters
Rigorous testing of switchgear before installation prevents field failures and ensures compliance with international standards (e.g., IEC 62271). The LQHV-430 addresses key challenges:
Time Efficiency: Reduces testing time compared to manual methods.
Safety: Minimizes risks during high-voltage energization.
Accuracy: Validates switchgear performance under realistic conditions.
Key Features of the LQHV-430
Multi-Power Output: Supplies various AC/DC voltages for diverse test scenarios.
Plug-and-Play Operation: Simple setup with intuitive controls.
Enhanced Safety: Built-in protections against overloads and short circuits.
Portable Design: Compact for factory-floor mobility.
Applications
Ideal for manufacturers testing:
High-Voltage Switchgear: Circuit breakers, disconnect switches.
Low-Voltage Panels: MCCBs, contactors, relay systems.
Combined HV/LV Cabinets: Integrated power distribution units.
