VLF cable test set HVA28/HVA28TD
High voltage cable test set VLF and DC
product code : RSKHVA28
product code : RSKHVA28TD
Smallest VLF & TD unit available
Smart VLF technology
Output voltage 28 kV
Patented cooling system
Dual Discharge Device (DDD®)
At only 14 kg this ultra light high voltage test set is the smallest unit available on the market and is perfectly suited for mobile use.
The HVA28 TD high voltage test set is protected by a watertight, crushproof and dust proof IP67-case.
The strong high voltage output can drive capacitive loads as high a 10 μF.
Possible output voltages:
Sinusoidal: 0 – 28 kV peak, 0 – 20 kV eff
DC: ± 0 - 28 kV
Squarewave: 28 kV
The HVA28 TD offers manual and automatic testing and diagnostic sequences and various operating modes such as:
VLF cable testing with symmetrical AC-Voltage (load independent across full range)
DC with positiv or negative polarity
Burn-/ Fault Condition or Fault Trip Mode
Jacket / Sheath Testing
Sheath Fault location mode
The Dual Discharge Device (DDD®) allows electronic and mechanical discharging of devices under test.
The following features make the HVA28 TD VLF high voltage test set the outstanding cable test and diagnostic system of its class:
Predefined standard-compliant cable test sequences
Symmetrical sine wave at high voltage
Measurement of the dissipation factor tan δ with an accuracy of ± 1 x 10-4
