Withstand voltage testing is an essential preventive test for electrical equipment, divided into AC and DC withstand voltage testing. AC testing includes power frequency, variable frequency, and 0.1Hz very low frequency testing, with the latter highly recommended by IEC for its significant advantages.

This 30kV generator withstand voltage tester is specifically designed for electrical equipment with large insulation equivalent capacitance, including power cables, power capacitors, and large to medium-sized generators and motors.

• Current, voltage, and waveform data directly sampled at high voltage side for accurate measurements
• Automatic shutdown within 20ms when output voltage exceeds user-preset limits
• Over-current protection on both high and low voltage sides with automatic protection based on set limits
• Built-in high voltage output protective resistor - no external resistor connection required
• High & low voltage closed loop negative feedback control circuit eliminates capacitive rise effect during output
