Predictive Diagnostics
Phase Assigning to a Channel:
As the InsulGard uses a variety of sensors that can be associated (directly or indirectly) with any phase
(or their combination thereof) of the electrical system, it is important that each sensor be assigned to a
correct phase. This is important for the accurate interpretation of PRPDD. For example, coupling
capacitor connected to B-phase should be assigned to the phase B.
Scroll setup parameters until
ChPHASE
appears.
Press
Enter
.
CH01
will appear. Press
Enter
.
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
Enter
. Use
keys to select another channel and repeat the procedure.
When done, press
Esc

Auxiliary Input Channels (Temperature, Voltage, and Current). Activating for Measurement
Suspend Mode:
NOTE: Activating options described below activate measurement suspend mode, if a parameter is
out of permitted boundaries. Pay attention to parameter LOW and HIGH levels.
Temperature
Scroll setup parameters until
InPt
appears.
Press

Trend Time Window:
The device allows providing an alarm based on both levels of PDI and Magnitude and on trend of these
parameters. The setting below sets a sliding time window represented in WEEKS for trend calculations.
At any time trend is calculated, the data is set weeks back from the current time and will be used for
trend.
Scroll setup parameters until
CALcSPd
appears.
Press
Enter
.
SPEEd- 18
will be displayed. Using
set required number of weeks for trend
calculation.
When done, press
Enter.
