InsulGard System Installation and Start Up Guideline

1.5. InsulGard system installation for a switchgear line
A Door mount InsulGard and two types of PD sensors (IPDS and RFCT) are typically used on switchgear lines.
Door mount InsulGard is usually installed on a switchgear compartment door. See door cut out dimension for IG
installation in Appendix 4. -
To minimize cables and conduits length, the best location for InsulGard installation
is in the middle of the installed sensors.
Insulgard must be reliably grounded at place of its installation
.
By default the temperature and humidity sensors are embedded in the Sensor Interface Board of the door mounted
InsulGard. External sensors are not required with this type of installation.
For PD sensors installation and their connection to InsulGard refer to sections 1.1
– 1.3.
Usually IPDS sensors capture PD pulses that originate in the cubicle where they are installed and the adjacent
cubicle. Because of this, IPDS sensors can be installed in every third cubicle. In practice, sensor location varies
depending on the installation.
The sensor location is typically specified in the configuration worksheet at the time of order entry.
More detail on what it represents and how to fill it in can be found in Appendix 3 -
If for some reason the position of the sensors was changed it is necessary to change the corresponding
sensor designation in the device database.
