Tan Delta and Partial Discharge diagnostics
HVA90 can be extended to a complete cable diagnostic system at any time.
HVA90
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. It performs VLF and DC testing, as well as sheath testing with sheath fault location mode.
Performance: Outstanding features considering size and weight vs. output load.
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.

CHARACTERISTICS
COMPACT AND PORTABLE
Our HVA series have been designed for maximum portability and on-site use. This makes them widely applicable for in-field use.
Dry System
HVA test sets are constructed with nonarcing contacts and no need to change the oil. This eliminates the routine servicing and makes the test sets almost maintenance-free.
