HV laboratory equipment
High-voltage test power supply 75kV 1A
Set in a HV test platform, this power supply allows performing tests and measurements on capacitive windings elements or the complete rotating machines.
To minimize energy consumption, size and cost of the equipment, it incorporates automatic compensation of reactive power and a series coupling / parallel.
Partial discharges free, this programmable high-voltage source can be used in production control of medium voltage cables.
The earth-isolated tank allows tangent delta measurements in the modes UST (ungrounded specimen test), GST (grounded specimen test) and GST-G (grounded specimen test with guard).
