What are you looking for?
Separate control and HV units
Continuously adjustable voltage
DC testing via a rectifier
In-built over-current protection
The AC voltage test sets are suitable for kinds of electrical products, electrical equipments and insulated materials, testing the insulated level of products, discovering the insulated situation of tested objects.
These units can also be upgraded to function as DC test sets by mounting the rectifier attachment on top of the transformer(optional).
Testing switchgears
Testing voltage and current transformers
Testing MV plants/components
The two piece design allows the operator to use the unit at a safe distance. The control unit is used to operate the high voltage transformer. The unit consists of a variac, current/ voltage display instruments, a timer for the test duration and a safety circuit.
