T3RC0600-HF and T3RC3000-HF SAFETY AND PRE-USE
CHECKS
The integrity of the insulation around the Rogowski coil itself must be VISUALLY
INSPECTED before use, and the T3RC0600-HF and T3RC3000-HF must NOT
BE USED if there are signs of damage.
When bending the exible coil around a conductor, avoid tight bends and sharp edges
that could damage the coil.
The voltage rating (safe PEAK working voltage) is clearly labelled on the cable
adjacent to the coil. For the T3RC0600-HF and T3RC3000-HF this is 5kV 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. The coil has a friction t, the coil is fully inserted
when the user feels they can ease the coil free end into the ferrule no further.
The voltage ratings are appropriate for intermittent use of the T3RC0600-HF
and T3RC3000-HF 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 5kV peak are
ash tested for one minute at 8kVrms 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 T3RC0600-HF and T3RC3000-HF must only be used with oscilloscopes or
monitoring equipment which have their BNC INPUTS PROPERLY GROUNDED.
