Ukraine, CIS [UA] HVT-70/50 is designed 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 50 kV at industrial frequency (f = 50 Hz).
The system can be used for both field and laboratory testing.
VERSATILITY
The system features both DC (rectified) and AC output voltage modes, which allows testing electrical equipment according to various standards using only HVT-70/50 system.
Output voltage mode is selected by a simple turn of a switch on the control unit - no additional equipment installation such as rectifier etc. is required.
SIMPLE CONTROL
The output voltage level and leakage current value are displayed on the easily readable and reliable pointer indicators.
In the AC output voltage mode, an additional measurement scale for the range from 0 to 1 mA allows recording the smallest current leakage.
TWO-MODULE DESIGN
The system comprises of two separate modules: the control unit and the high-voltage unit.
The test process is controlled from the control unit while an object under test is connected to the high-voltage unit.
Such two-module design allows an operator to remain at a safe distance away from the high-voltage circuit and the object under test.
BUILT-IN DISCHARGE DEVICE
The high-voltage unit is equipped with an automatic grounding device – an auxiliary protective solution for discharging an object under the test and the high-voltage circuit of the system.
PORTABLE TEST SYSTEM
Small weight, compact size and portable design of both units of the system enable rapid deployment, quick reconnection and operational comfort during the field testing.
The system can be supplemented with a convenient trolley for easy transportation.
OIL INSULATION
The high-voltage unit contains a step-up transformer with oil insulation which works reliably under almost any conditions and does not require extra care or special maintenance.
