Product Summary

 

High voltage cable test set VLF and DC

 

product code : RSKHVA28

product code : RSKHVA28TD

Price: TBA

Smallest VLF & TD unit available

14kg only

Smart VLF technology

Output voltage 28 kV

 

IP67 watertight

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

RMS measurement of output voltage and current

Measurement of capacitive and resistive load

Automatic load dependent frequency selection (0.01 Hz – 0.1 Hz)

Display of current test time

Integrated real-time scope function

Self-explanatory, multilingual software

Automatic measurement reporting

Computer-Interfaces and report storage via USB or Bluetooth

PC software (HVA Control Center) for data analysis and storage

Flashover detection and ultra fast switch off
