unlimited operating time
HVA test sets are designed for continuous operation without any thermal limitations.
HVA94
The HVA94 is a compact and portable VLF test set designed for assessing the condition of medium-voltage cables up to 46 kV (in accordance with IEEE 400.2). Its robust design and excellent power-to-weight ratio make it a reliable choice for routine cable testing in the field. In addition to VLF testing (sine and square wave) and DC testing, the HVA94 also supports sheath testing and sheath fault location (additional sheath fault locator needed).
Performance: Outstanding performance considering size and weight vs. output load. Devices under test up to 4 km in length can be tested at 66 kVrms with 0.1 Hz (at 250 pF/m cable capacitance and 0.9 μF load).
Safety first: Two simultaneous ways of discharging (electronic and mechanical) plus integrated 12 kV backfeed protection (at 50/60 Hz) ensure maximum operator safety.
Connectivity: On-site, no laptop is required. All results can be later downloaded via USB for further analysis and easy reporting using the b2 ControlCenter.
Flexible connection options: Robust HV connectors allow the use of various HV test lead lengths, quick replacement, and easy upgrades for diagnostic system integration.

CHARACTERISTICS
Dry System
HVA test sets are constructed with non-arcing contacts and no need to change oil. This eliminates the routine servicing and makes the test sets almost maintenance-free.
COMPACT AND PORTABLE
Our HVA test sets are designed for maximum portability, resulting in widely applicable devices for any type of on-site use.
