HVA94 VLF high voltage test set Datasheet The HVA94 is a perfectly suitable test set to determine the condition of medium voltage cables with a voltage rating up to 69 kV (acc. to IEEE 400.2-2013). Its compact design and unmatchable high voltage output power to weight ratio is second to none on the market and makes it an excellent option for cable testing up to 66 kVrms and 94 kVpeak (sine wave operation). Beside the VLF and DC testing, the HVA94 performs also sheath testing with sheath fault location mode (here, however, additional fault probe is needed). 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 downoaded via USB for further l 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 of a replacement cable, or a simpler upgrade path for connection of diagnostics systems.

YOUR BENEFITS TD AND PD DAGNOSTICS HVA94 can be extended to a complete cable diagnostic system at any time. DRY SYSTEM HVA test sets are constructed with nonarcing 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. COMPACT AND PORTABLE Our HVA series have been designed for maximum portability and on-site use. It makes them widely applicable for in-field use. • Pure sinusoidal output voltage (load-independent) • Sheath fault pinpointing in combination with sheath fault locator (not included) • Easily exchangeable HV test lead • Breakdown voltage and load detection • Real time oscilloscope of the output voltage on the HVA display • Programmable test sequences with a tailor-made software tool • Report downloads from the device via USB flash drive
