Parallel Resonant AC Dielectric Test Sets up to 250 kVa

PAR Series

The PAR Series of Parallel Resonant Test Sets offer the best alternative available for AC high voltage testing high capacitance loads, like large motors & generators, MV cables, large apparatus, iso phase bus, etc. These models are designed to provide a Variable Inductance Parallel Resonant high voltage source used to test very high capacitance loads. Through tuning the variable inductance of the high voltage reactor to match the capacitive reactance of the load, the apparent power required to test the load is nearly eliminated, greatly reducing the input power required from the test set and from the input lines. Models available from 8 kVac – 250 kVac @ 50 kVA – 300 kVA load and suitable for 50/60 Hz.


Alternate AC Voltage Technology Product Line to Consider

Very Low Frequency (VLF) AC Test Sets

The VLF & VLF E Series are 0.1 Hz. – 0.01 Hz. AC output hipots for testing very high capacitance loads, like MV/HV power cables and large rotating machinery, that would require hundreds of kVA of test power at 50/60 Hz. Models from 30 kVac – 200 kVac and load rated from 0.1 uF – 50 uF.


AC Hipot product lines available from HVI

HVI also produces many lines of AC Dielectric Test Sets to serve the  multitude  of  applications  needing AC Withstand or Diagnostic testing, like Partial Discharge and Tan Delta. These lines range from small, portable 1 kVA – 3 kVA hipots  to  field mobile 15 kVA models to 40kVA models for factory use. Some models are < 5pc in PD output and some are CE marked.
