Predictive Diagnostics
1. Coupling Capacitor 3 - 5 nC/Volt (3)
2. RFCT on cable drain shield 5 - 10 nC/Volt (10)
3. RFCT on surge capacitor ground 3 - 5 nC/Volt (5)
4. RTD sensor in motor/small generator (none of
spiral shields on RTD wires) 5 – 15 nC/Volt (10)
5. RTD sensor in large generator in spiral shields 50 –
70 nC/Volt (50)
6. RFVS sensor in switchgear 10 – 20 nC/Volt. (15)
Channel Phase
Sensors connected to a particular channel are in most
cases associated with some phase. For example, a
coupling capacitor connected to the phase B should be
associated with phase B. Set associated phase to all
active channels.
In some cases a sensor senses all three phases (example,
RFVS sensor in SWG). There is not a phase association
in such a case - leave the phase A.

will appear.
Use
keys to set the phase assignment for the current channel. The
options available are: A, B, C, AB, AC, BC.
When done, press
