Large output load capability up to 5 μF
The HVA120 has the highest power to weight ratio of any comparable unit. Apart from their variable frequency VLF output, the operator can also select dual polarity DC and cable jacket or sheath testing output modes. It also features both electronic and mechanical discharging of devices under test (DDD®), a 12kV feedback protection system and an unlimited duty cycle (dry system – no oil used) completing the performance of this out-standing HV System. The HVA120 can be upgraded with a Tan Delta (TD) Diagnosis System and a Partial Discharge (PD) Diagnosis System (both optional).
