Small and lightweight
The HVA series offers the smallest and lightest VLF hipot test sets available. This makes them widely applicable for in-field use.
HVA28 & HVA28TD
The HVA28 and HVA28TD are truly compact and portable VLF test sets that determine the condition of medium voltage cables. Both test sets perform VLF and DC testing, as well as sheath testing with sheath fault location possibilities. In order to meet international test guides (e.g. IEEE 400.2-2013) the HVA28TD combines the small and lightweight VLF test set with an integrated Tan Delta diagnostics unit.
Performance: Outstanding features considering size and weight vs. output load.
Duty cycle: No thermal limitation! You can use the test set continuously.
Safety first: Two independent discharge devices (electronic and mechanical discharging) and an integrated 12 kV backfeed protection system (at 50/60 Hz).
Connectivity: On-site, no external PC is needed. All results can be later downloaded via USB or Bluetooth for further investigation and easy reporting via the b2 ControlCenter.
MWT: In addition, HVA28TD offers a Monitored Withstand Test, a combination of withstand testing and Tan Delta diagnostics in compliance with the guide IEEE 400.2-2013.

Characteristics
Dry system
HVA test sets are constructed with non-arcing contacts and no need to change oil. This eliminates routine servicing and makes the test sets almost maintenance-free.
Unlimited operating time
HV generators are designed for continuous operation without any thermal limitations.
