HVA34-1 & HVA34TD-1

VLF high voltage test set

The HVA34-1 and HVA34TD-1 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 HVA34TD-1 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 transient 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 Control Center.

MWT: In addition, HVA34TD-1 offers a Monitored Withstand Test, a combination of withstand testing and Tan Delta diagnostics in compliance with the guide IEEE 400.2-2013.
