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 Flashover voltage measurement Time optimized burning mode No regular maintenance required, due to dry (oil-free) system Unlimited duty cycle
The fully comprehensive safety features guarantee protection of operators and test instrument.
Short circuit protected output 12 kV feedback protection Signal lamps for active / inactive high voltage Status display of safety functions Integrated discharge circuit (DDD®) for device under test Main switch with key-lock Emergency-off button on front panel
A SINGLE VLF high voltage test set for NUMEROUS applications:
Cables: XLPE , PE, EPR, PILC, etc. Capacitors Switchgear Transformers Rotating machines (IEEE 433) Isolators Bushings
In connection with the PD30E, the HVA28 TD VLF high voltage test set may be expanded into a partial discharge measurement system. |
