HVDC Polarity Reversal Testing in high voltage DC test voltages for routine, type and development test on components and complete systems found in electrical power supply systems and operating on DC voltage (HV transmission systems etc).
The M-series high voltage DC test systems are designed to test systems with higher currents ranging up to 2A, such as for outdoor or pollution testing. And the DC voltage test systems are generally equipped with polarity reversal. They are used for withstand DC voltage or polarity reversal testing according to IEC or other national standard. Also they can be used as HVDC charging power for capacitor banks etc.
Features with low ripple on voltage, rapid polarity reversal, and can upgrades for the DC test system to measure partial discharges of the test system at low background noise levels
Normal HV DC voltage test system consists of HVAC charging power, doubling capacitors, rectifiers, smoothing capacitors and resistive voltage divider. HVAC voltage will be rectified to HVDC test voltage by means of an appropriate electric circuit.
High-voltage DC testing for transformers, cables, bushings, switchgears, etc.
Wet and pollution testing
DC current measurements at high-voltage potential
Charging capacitor banks for high-performance testing
Special testing, for example, for bipolar testing of overhead lines
