3.3 SA 32
The SA 32 offers the possibility of fault location according to the Secondary Impulse Method
(SIM) respectively SIM-MIM (advanced SIM).
In conjunction with a surge voltage generator type SSG, the SA 32 can be used as DC
testing generator up to 32kV, or as fault conditioning instrument up to max. 250mA. Burning
operation possible up to 850mA (SSG 1500 / 2100)
A pull switch 4 enables selection between surge and testing operation.
Furthermore, the SA 32 has an incorporated milliammeter with protection device and decade
3-step range switching.
The SA 32 includes a solid (direct) earthing unit for earthing of high voltage connection cable.
This is made approx. 3 seconds after switching off of instrument. The discharging process
(discharging to earth via resistor) is done by SSG. Release of earth pin ball is clearly audible.
Discharging of the cable is also on the discharge contactor box affected in case of power
failure or after release of micro switch control.
3.4 SA 32 K
The SA 32K has been especially developed for installation into a cable test van, together
with high voltage pressure tester and switching and earthing device.
Please note unlike the SA 32 this unit has no solid earthing and no milliammeter.
The pull switch 4 on the SA 32K is used for extend the surge voltage pulse period. This is
advantageous in case of very high surge voltages and for measurements on long cables.
3.5 High voltage socket board CS 32/2
The CS 32/2 is a high voltage connecting device between SA 32 and the high voltage cable.
It is designed to operate up to voltages of 32kV DC. Additionally, 4mm low voltage sockets
are provided for connection of smaller instruments up to 2,5kV output voltage with the high
voltage cable (e.g. IRG 2000 TDR, audio frequency generator, megohmmeter....)
The micro switch control at the high voltage output of the CS 32/2 is a safety device which
interrupts the power supply to the SA 32 and SSG if the high voltage cable is not connected.
The Syscompact can be operated with connected high voltage cable only.
Unscrewing the cap of HV plug initiates a discharge and the grounding of the connected HV
cable and the fault location system. The unscrewing time of 10sec. is sufficient for full
scharging and grounding of the unit.
In CS 32/2, 2 plug-in sockets 220V are incorporated. These plug-in sockets are directly fed
with 220V mains voltage.
