InsulGard System Installation and Start Up Guideline
4
1. InsulGard System Installation
Always refer to the user manuals included on the Flash drive with the Insulgard. Full set of user manuals are
available for download at
Installation of the
InsulGard (IG
) system is based on the physical layout of each monitored object and may include
variations. The typical installation for rotating machines and switchgears is described below.
InsulGards are generally not interchangeable devices
. Sensors configurations can vary significantly from project
to project. The InsulGard typically comes preconfigured in based on the configuration worksheet received from the
customer at the time of order entry (see Appendix 3
– add link). Be sure that the Insulgard device is designated for
this particular project and to be connected to this particular set of sensors. Switching InsulGard devices can require
significant reprogramming of database software and InsulGard firmware settings and can lead to errors.
Each installation includes installation of InsulGard (Section 1.1 -
), partial discharge (PD) and external auxiliary
) and their connection to Insulgard monitor. Also some external interfaces can be
connected to the Insulgard to remotely get information about the monitor and monitored object condition.
This installation can be done only on
de-energized equipment. ALWAYS use appropriate safety practice to
ensure safe work!
1.1. InsulGard installation and external connection.
Your InsulGard device has two parts: Monitor and Sensor Interface Board connected by a flat ribbon cable.
Cables from PD and Auxiliary sensors must be connected directly to the Sensor Interface Board.
1) InsulGard installation options:
a) On the panel in NEMA-4X enclosure with or without transparent windows for outdoor installation (Fig. 1-1a).
This enclosure can be installed before the equipment is de-energized.
b) On a panel (Figure 1-1b) for installation into any custom cabinet including explosion-proof enclosure.
c) Door mount InsulGard (Figure 1-2) with the Sensor Interface Board installed on the back of the InsulGard unit
itself. Usually, this type of assembly is used for indoor installation on a switchgear door. Door cutout
dimensions are in Appendix 4 -
