HPG 70-K
The high voltage test set HPG 70-K from SebaKMT is a fully insulated test set for DC testing up to 70 kV. Thanks to its fully insulated design this system is ideal for stand-alone applications. The DC voltage is obtained through a bridge rectifier which ensures a very low ripple of the test voltage. Moreover the DC voltage is measured on the secondary side and therefore ensures a precise output voltage.
Typical application areas:
- Testing of cables
- Testing of switchgear
- Testing of current-transformers
- Testing of MV plant/ component testing
Key benefits:
- Highest safety thanks to fully insulated design
- Compact and lightweight
- Separate control and HV-unit
- Voltage continuously adjustable
- Expandable with a VLF CR attachment for VLF testing on MV cables
System description
SebaKMT’s high voltage test set HPG 70-K is a fully insulated
test set for DC testing up to 70 kV. Thanks to its fully insulated
design, this system is ideal for stand-alone applications. The
DC voltage is obtained through a bridge rectifi er which
ensures a very low ripple of the test voltage. Moreover, the
DC voltage is measured on the secondary side and therefore
ensures a precise output voltage.
The high voltage test equipment HPG 70-K consists of two
parts and is used for testing of cable installations either as a
stand-alone unit or built into a module or cable test van. The
control unit HSG 1 includes a variac. Its output voltage feeds
the high voltage unit HVT 70.
The high voltage unit HVT 70-K is fully insulated. The test
voltage of 70 kV DC is drawn from a socket outlet and plug
and fed to the cable under test. For feeding of the control
voltage of 0 … 230 V AC, a multi-pole connection lead to the
control unit is supplied.
For testing of polymer insulated cables the test system can
be expanded with a VLF CR attachment. This attachment
will allow high-capacitance testing up to 54 kV at 0.1Hz.
