Overview
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 HVA90 is a compact and portable VLF test set which determines the condition of medium voltage cables. At 1µF DUT load, the unit can drive an impressive 64kVrms at 0.1Hz . It performs VLF and DC testing, as well as sheath testing with sheath fault location mode. Cable testing, cable sheath / jacket testing, sheath fault location, cable fault conditioning (burning), vacuum bottle test.

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.
