GR-60 AC hipot

The GR-60 AC hipot by GRAMPUS is a portable 0.1 Hz VLF cable test system for the testing of medium voltage cables.

At only 57 kg this compact AC hipot is truly quite remarkable and as such is ideal for mobile use.

The powerful output is capable of driving capacitive loads of up to 10 μF.

At maximum output voltage cables with a length of up to 15 km can be tested.
Possible output voltages:

Sinusoidal: 0 – 62 kV peak, 0 – 44 kV eff
DC: ± 0 – 60 kV
Squarewave: 60 kV

The GR-60 AC hipot offers various operating modes.
Cable testing, cable sheath / jacket testing, sheath fault location, cable fault conditioning (burning), vacuum bottle test.

The following features make the GR-60 AC hipot the outstanding cable test system of its class:

Predefined standard-compliant cable test sequences
Symmetrical sine wave at high voltage
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
Report storage via RS232 or USB optional
PC software (b2 ControlCenter) for data analysis and storage
Flashover detection and ultra fast switch off
Flashover voltage measurement
Time optimized burning mode
No regular maintenance required

The fully comprehensive safety features guarantee protection of operator and test instrument.

Short circuit protected output
12 kV feedback protection
Signal lamps for active / inactive high voltage
Status display of safety functions
Dual Discharge Device DDD®, elektronische und mechanische Entladeeinrichtung (integriert)
Main switch with key-lock
Emergency-off button on front panel

A SINGLE device for NUMEROUS applications:

Cables: XLPE , PE, EPR, PILC, etc.
Capacitors
Switchgear
Transformers
Rotating machines (IEEE 433)
Isolators
Bushings

The GR-60 AC hipot may be expanded with optional devices into to a full cable diagnostics system.

The GR system may then be used for tan delta measurement
