GIT-450kVA/150kV PD-free AC Dielectric Test Set

Automatic mode

•10-inch color LCD display, programmable controller PLC automatic control.

•HV voltage, HV current, LV voltage, LV current are collected isolate and synchronously, with high-precision sensor and high-performance collection chip.

•The human-machine interface adopts full touch and partial key operation mode, intelligent work process, automatic mode and manual mode for option.

•HV voltage, HV current, LV voltage, LV current, time and the HV curve dynamic can be displayed, clear and obvious.

• With over-voltage, over-current protection, and flashing protection. Set the output voltage, high voltage protection current, low voltage protection current (hardware is set up), milliammeter protection current and timing.

• Support stage boost (5 stages), and the voltage value of each stage can be set arbitrarily, making it easier to find test product problems.

• Zero-starting function. Test can be proceeded after the voltage is back to zero.

•With a local storage space of 8,000 records/3 months and provides a USB interface for exporting data to an external USB flash drive.

• When setting voltage is arrived, it will be timing automatically. After timing, voltage will be back to zero.

• When the HV current and LV current are over setting value, the voltage will be cut off automatically and it will be back to zero. When the flash-over setting value is exceeded, the voltage will be cut off automatically and back to zero.

•Software and hardware anti-interference design, adapting to the harsh electromagnetic environment.

• Automatic error diagnosis, easy to discover and solve problems, with simple and convenient maintenance.

Manual mode

• Monitoring functions: HV voltage, LV current, HV current, compensation current, zero indication, power indication, operating indication, and timing indication.

• Protection functions: Over-current protection, zero position start protection, and audible and visual alarms.

• Adopts a new time relay with a wider timing range (1S to 99 H).

• Adopts a new current relay.•
