Voltage test bench UHV-316D

leakrotation directioncurrent

Product introduction:
The UHV-316D stator test system is designed for production and R&D testing of single-phase and three-phase generator stators. It supports 3‑wire, 6‑wire, 9‑wire and 12‑wire windings, uses a 2‑channel wiring method and is suitable for testing 3‑wire and 6‑wire stators of new energy motors up to frame H355.

Standard test items:

• DC resistance test
• Insulation resistance test
• Inter-turn insulation (impulse) test
• Power-frequency withstand voltage test
• Winding current balance test
• Rotation direction test

Optional test items:

• Inductance measurement
• Current balance test
• Magnetic field rotation direction test

Product characteristics:

• Simultaneous result display with built-in data storage and printout functions
• Foot-operated safety switch for safe operation
• Front-end test fixture designed for medium and small stators
• High-speed measurement suitable for production lines (home appliance motors, water pump motors, etc.)
