Voltage test bench UHV-316D

currentrotation directionresistance

Product introduction:
The UHV-316D stator test bench is designed for testing single-phase and three-phase generator stators and supports 3‑wire, 6‑wire, 9‑wire and 12‑wire winding configurations. It 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 (DC 500 V)
• Inter-turn insulation test
• Power-frequency withstand voltage test (AC up to 5000 Vac)
• Winding current balance test
• Rotation direction test

Optional test items:

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

Product characteristics:

• Simultaneous result display with built-in data storage and print functions
• Foot-operated safety switch for operator protection
• Front-end test fixture suitable for medium and small stators
• High-speed measurement designed for mass-production environments
