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 member of the HVA series with extra power, with an output current up to 120 mA. This extends greatly the maximum load and therefore the testable length of a cable. It is a compact and portable VLF test set for assessing the condition of medium-voltage cables up to 25 kV (in accordance with IEEE 400.2). In addition to VLF testing (sine and square wave) and DC testing, the HVA40-5 also supports sheath testing and sheath fault location (additional sheath fault locator needed).
Extra power: Outstanding performance considering size and weight vs. output load. Devices under test more than 15 km in length can be tested at 32 kVrms with 0.1 Hz (at 250 pF/m cable capacitance and 3.8 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 routine servicing and makes the test sets almost maintenance-free.
unlimited operating time
HVA generators are designed for continuous operation without any thermal limitations.
