Page 4: Insulgard System Installation
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. - Page 5 Sensor Interface Board Figure 1-2. a, b – front and back view of Door mount InsulGard, c, d - front and back view of IG installed on a switchgear cabinet door. For a panel mount InsulGard, the Sensor Interface Board is installed on the panel under the Monitor. For sensor connections, it is necessary to temporarily remove the Monitor from the panel.

- Page 7 InsulGard System Installation and Start Up Guideline A door mount InsulGard has the same wiring diagram as a panel mount, but without Din-Rail terminals. The power supply voltage is connected straight to the power input of the unit. Door mount InsulGard installed on switchgear compartment door usually has internal temperature and humidity sensors and doesn’t need external sensors.
- Page 8 Eaton at the time of order entry. Settings can also be verified in InsulGard software: → section "Unit Settings" → "Settings for Channel".NOTE: It is important that the coupling capacitor installed on phase A is connected to Channel #1 to obtain phase reference for the InsulGard hardware and firmware.
- Page 9 11) AC power connection and connection to relays, to RS485 and 4-20mA interfaces Use green plugs on the right side of the InsulGard (Figure 1-6 and 1-8). The green plugs can be wired when the InsulGard is not installed on its panel yet.

Monitored object and InsulGard must be de-energized. The best way to de-energize InsulGard is to de-energize the incoming power supply line. On a panel mount InsulGard open the fuse located on the DIN-Rail. All sensors have default cable length of 65’ (20m). Custom lengths may be specified at the time of order entry. - Page 11 InsulGard System Installation and Start Up Guideline IPDS - Integrated Partial Discharge Sensors IPDS sensors are 80pF coupling capacitors (CC) with voltage ratings from 5kV to 38kV and special protection PCB board built in. For sensor installation: a) Sensor must be reliably grounded.
- Page 12 Primary CT secondary winding. CTF is used if there is no metering CT in feeder termination compartment and corresponding metering CT is too far from the InsulGard. Install CTF around a feeder cable of any phase in a motor feeder termination enclosure. It must be installed over the shielded part of the feeder cable with cable shield grounding wire coming through the CT.

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. -

StartUp Procedure Guideline does not replace InsulGard and its sensors Manuals. The procedures described below Required Items The following items and set of documentation shipped with InsulGard are required for the functionality tests and start - Set of documentation shipped with the InsulGard(s) and sensors:... - Page 20 4. Device setting may be modified by third party if it was an indirect shipment. Or devices assigned for different projects or for different locations for the same project could be switched. Verify that the proper Insulgard device has been installed. Commonly there is a sticker on an InsulGard face plate with name of the object and device address.

Page 21: Verifying/Correcting Configuration
Set Correct Date and Time The time and date on the InsulGard was set in Minneapolis, Minnesota. Local time and date must be entered. Also if a device has spent too much time on a shelf, backup clock battery can be discharged and date/time corrupted: 1. - Page 22 6. Send setting to the device. Calibration/Verification procedure Use GKI-2 pulse generator by Eaton to inject pulse in common mode between the HV conductor and ground using cable with alligator clips. If different pulse generator used, set the generator pulse parameters: Pulse Magnitude ~10 Volt, Pulse Width –...
- Page 23 Figure 2-1 Calibration Verification steps 1. Switch the generator ON and run “Single Measurement” from Communications tab of the InsulGard software. A measurement time is proportional to the number of active channels and will take approximately 1.5 minutes for maximum 15 active channels.

Page 24: Baseline Measurement On Energized Object
2.5 Baseline Measurement on Energized Object At this point all signal cables are connected and the InsulGard is powered up, the equipment energized and running and the software is installed on the PC. Data base configuration is verified and corresponds to the application. - Page 25 Potential Transformer or from any source with known phase shift to HV system voltage – see Appendix 7 of InsulGard User Manuals. Reference signal must not exceed 5VAC RMS – use appropriate divider to bring reference signal into preferable range of 0.1-1 VAC. This operation should be performed one time considering that InsulGard power and system voltage connections have not been changed during monitoring.
