Instructions
The voltage rating (safe PEAK working voltage) is clearly labelled on the cable
adjacent to the coil. For the T3RC3000-LF and T36000-LF this is 10kV peak. Never
use at voltages greater than this value.
Voltage ratings are only valid if the ‘free end’ of the coil is fully inserted into the socket,
and remains fully inserted during use i.e. right up to the black indicator line on the free
end of the coil.
The voltage ratings are appropriate for intermittent use of the T3RC3000-LF
and T36000-LF as a test instrument and not for continuous use in a
permanent installation.
The ratings are derived from the following standard test: Coils rated for 10kV peak
are ash tested for one minute at 15kVrms using a 50Hz sine-wave voltage.
For permanent installation the coil should be situated such that corona, which will
eventually damage the coil insulation, cannot occur. For information regarding
permanent installation of Teledyne Test Tools Rogowski coils on high voltage
equipment please consult Teledyne Test Tools.
The user must ensure that the absolute maximum rated di/dt is not exceeded
THE INTEGRATOR
The Rogowski probe must only be used with oscilloscopes or monitoring equipment
which have their BNC INPUTS PROPERLY GROUNDED.
SAFETY AND PRE-USE CHECKS FOR ALL TELEDYNE TEST
TOOLS ROGOWSKI PROBES
The Teledyne Test Tools Rogowski probes do not provide protection of
the user from electric shock whilst applying or removing the probe from
HAZARDOUS LIVE conductors. Additional protective means are
necessary to avoid electric shock from HAZARDOUS LIVE conductors
which cannot be de-energised.
If HAZARDOUS LIVE voltages are present and accessible in the
installation, appropriate protective equipment must be used.
The Rogowski coil must not be used if the coil outer layer is damaged or in
any way compromised.
The Teledyne Test Tools Rogowski probes must only be used in
conjunction with properly earthed test equipment.
If the Teledyne Test Tools Rogowski probes are used in a manner not
specied by the manufacturer the protection provided by the equipment
may be impaired.
