True Modularity
HVA68TD can be easily extended to a complete cable diagnostics system by adding products from our PD or PDTD series at any time.
HVA68TD
Get to know the HVA68TD
the new member of our smartvlf® series
The HVA68TD is a truly compact and portable VLF test set that determines the condition of medium voltage cables with a voltage rating up to 46 kV (acc. to IEEE 400.2-2013).
It performs VLF and DC testing, as well as sheath testing with sheath fault location mode (additional fault probe needed).
The high output power of the HVA68TD expands greatly the load possibilities. It allows testing longer cables or several phases in parallel. The integrated Tan Delta diagnostics unit enables a straightforward condition assessment of the cable system.
The new HVA68TD is more than just a VLF tester. In addition to VLF testing & Tan Delta diagnostics capability, it allows to pre-locate arcs in the cable insulation. This makes the HVA68TD the smartest VLF test set available.
Arc Pre-Location (APL)
A new dimension for VLF testing
VLF withstand tests are used to detect weaknesses in the cable insulation. While a healthy cable is passing the voltage withstand test unharmed, a cable with pre-damaged insulation will break down during this test, resulting in an arc.
Arc Pre-Location information adds additional value to traditional VLF testing, which helps to save time and cost in the subsequent cable fault location process.
Performance: Best in class output power combined with outstanding TD diagnostics features.
Safety first: Two independent discharge devices (electronic & mechanical) plus an integrated 12 kV backfeed protection system (at 50/60 Hz).
MWT: Combination of withstand testing & Tan Delta diagnostics in compliance with guide IEEE 400.2 - Monitored Withstand Test.
Connectivity: On-site, no external PC is needed. All results can be downloaded later via USB or Bluetooth for further investigation and easy reporting with the b2 ControlCenter software.
Flexible high voltage connection options: Our high voltage test leads enable a simple and safe connection between HVA and the test object. They are available in different lengths and are quickly exchangeable.
CHARACTERISTICS
unlimited operating time
HVA test sets are designed for continuous operation within the specifications.
Arc Pre-Location (APL)
The integrated APL function provides failure distance in case of a breakdown during VLF testing. This adds additional value to traditional VLF testing, which saves time and cost in subsequent cable fault location processes.
