The compact design and unmatchable high voltage output power to weight ratio of the HVA test sets are second to none on the market, and make the b2 electronics high voltage generators very desirable in all classes at all voltage levels.
The HVA30-7 is a compact and portable VLF test set which determines the condition of medium voltage cables. It performs VLF and DC testing, as well as sheath testing with sheath fault location mode. It is also an HVA series member with very high output current, up to 120 mA.
Performance
Outstanding features in terms of output load.
6.0 μF @ 0.1 Hz @ 24 kVrms in comparison to 0.5 μF @ 0.1 Hz @ 24 kVrms (HVA34)
Duty cycle
Operating time of this test set is not thermally limited; it may operate continuously.
Safety first
The test set has two independent earthing devices (electronic and mechanical discharging) and an integrated 12 kV transient protection system (at 50 Hz) to protect both the operator and the device.
Connectivity
On site, no external PC is needed. All results can be later downloaded via USB for further investigation and easy reporting via software tool.
Solid HV connectors
Robust HV connectors allow the use of various HV test lead lengths, quick exchange of a replacement cable, or a simpler upgrade path for connection of diagnostics systems.
Service and maintenance
With no oil or arcing contacts, the dry-type transformer makes this test set almost maintenance-free.
