HVT-70/50-70kV Manual AC DC Hipot Tester

Manual AC DC Hipot Tester

Portable high-voltage test system HVT-70/50 DC/AC HIPOT is an effective and cost efficient solution for high-voltage testing of solid dielectrics with low and medium electric capacitance (power cables, switchgear, surge arresters, busbars, insulators, etc.) with DC (rectified) voltage up to 70 kV and high voltage testing of other objects with AC voltage up to 50kV RMS at industrial frequency (f = 50 Hz).

Output voltage type is selected by a simple turn of a switch on the control unit-no additional equipment installation is required.

The system comprises of two separate modules - a control unit and a high-voltage unit. The control unit is powered from industrial mains and used to control the high-voltage unit from a safe distance. Output voltage and current are displayed on the reliable and easily readable analog pointer indicators. The high voltage unit contains a step-up transformer with oil insulation.

The system features an overcurrent and overvoltage protection and is equipped with a built-in automatic grounding bar

Frequently Asked Questions (5 answered questions)

Person name: Asian

HVTS HIPOT allows set Voltage and current limits and Voltage ramp rate.
In AUTO control mode there is a shortcut to further limit the test voltage within the boundaries of the selected pre-set, allowing testing upto desired voltage levels eg 10kV or 40kV
Ramp up can be set in range 0.5 … 4.0 kV/s, step 0.5 kV/s.

Ripple is automated in HVTS thanks to its design.
HVTS automatically adjusts the position of internal voltage regulator if the voltage from the mains fluctuates by more than 1.5V (higher or lower from the moment test was started and output voltage was raised), so the output voltage will be as stable as possible. it will adjust Voltage regulator position 1 turn of the coil up or down that is equal to approx. 0.5kV of output. Accordingly, in the AC mode your ripple is less than 2% ; In case of DC Max value will less than 1%.

Withstand or hipot testing is used to evaluate the condition of as example cable insulation during installation, acceptance, or maintenance testing or as another example capability of a material substrate which is to be used in an electrical environment to function upto its rated voltage.

HVTS Hipot provides a Digital display incorporating both volt and current readings. Readings are displayed as values and can also be emulated per user option as an analog type display on the LCD.
