Tan Delta and Partial Discharge diagnostics
HVA40-5 can be extended to a complete cable diagnostic system at any time.
HVA40-5
The HVA40-5 is a truly 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 (additional fault probe needed). It is also an HVA series member with a very high output current, up to 120mA, extending greatly the load possibilities and testable length of a cable.
Performance: Outstanding features considering size and weight vs. output load.
4.6μF @ 0.1Hz @ 29kVrms in comparison to 1.1μF @ 0.1Hz @ 29kVrms (HVA45)
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 12kV backfeed protection system (at 50/60Hz).
Connectivity: On-site, no external PC is needed. All results can be later downloaded via USB for further investigation and easy reporting via the b2 ControlCenter.
Solid HV connectors: Robust HV connectors allow the use of various HV test lead lengths, quick exchange through a replacement cable, or a simpler upgrade path for connection of diagnostics systems.

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
HVA generators are designed for continuous operation without any thermal limitations.
