HVA34
VLF high voltage test set

 
 

The HVA34 is a perfectly suitable test set to determine the condition of medium voltage cables with a voltage rating up to 25 kV (acc. to IEEE 400.2).
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 24 kVrms and 34 kVpeak (sine wave operation). Beside the VLF and DC testing, the HVA34 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 backfeed protection system (at 50/60 Hz) provide the best possible protection for the user 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 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.

Output voltage max. 34 kVpeak, 24 kVrms
Output load 0.4 μF @ 0.1 Hz @ 24 kVrms
DOUBLE POWER 0.9 μF @ 0.1 Hz @ 24 kVrms
Weight 20 kg / 44 lbs
 

CHARACTERISTICS

 

unlimited operating time

HVA test sets are designed for continuous operation without any thermal limitations.

 

COMPACT AND PORTABLE

Our HVA series have been designed for maximum portability, resulting in widely applicable devices for any type of on-site use.

 

Dry System

HVA test sets are constructed with non-arcing contacts and no need to change the oil. This eliminates routine servicing and makes the test sets almost maintenance-free.

 

Tan Delta and Partial Discharge diagnostics

HVA34 can be extended to a complete cable diagnostic system at any time.
