OVERVIEW

QualiTROL ETM With Direct Winding Temperature MeasurementThe QualiTROL Electronic Transformer Monitor (ETM) for Liquid-FilledTransformers (Model #509-100 Series) is an Intelligent Electronic Device (IED)that combines microprocessor technology and advanced digital signal processing,to accurately assess the health, and performance of three phase orautotransformers.

The 509 can be tailored to suit the application. The ETM can monitor up to eighttotal parameters. Requiring inputs from Resistance Temperature Detectors(RTD’s), Current Transformers, AC Voltage (0-140 VAC or 0-320 VAC),Current loops (0-1 or 4-20 ma DC) Voltage (0-100 mv or 0-10V) Switch

The ETM with direct winding measurement is extremely easy to install and use.It is designed to be mounted outdoors (heater available inside enclosure), in the

transformer control cabinet or in a 19 inch control rack. The ETM is powered bya universal power supply of 90-264 VAC 47-63 Hz single phase power or 40-290VDC while the Converters for the fiber optic probes uses 100-240 VAC. Itcomes with user-friendly computer aided setup software and can be supplied witha wide array of customer selected sensors. For hardware specific questionsconcerning the 509 see the 509 Operations Manual IST-072-X and forconfiguring the software of the 509 see the 509 Software Manual IST-073-X.

About This Manual

This manual provides all the information you will need to install the fiber optic probes, connect the converts to the probes and 509 ETM and configure yourQualiTROL Electronic Transformer Monitor. It is organized into the followingsections:

Modifying Radial Spacers — Explanation of how to modify the transformerwinding spacers to accept the fiber optic probes.

Fiber Optic Probes — Information and dimensional characteristics concerningthe Fiber Optic Probes.

Transformer Tank Feed-Thru Plates — Drawings and instructions formounting the Feed-Thru Plates.

Feed Thr Connectors Where to install the Feed Thr Connectors




Installing Fiber Optic Probes in the Radial Spacers

Modifying Radial SpacersThe Qualitrol Fiber Optic Probes come equipped with a keyed tip. This tip once

placed inside the modified radial spacer will lock itself in place for the life of the probe. For an example of a modified spacer and the appropriate dimensions see below.




Fiber Optic Probes

Transformer Tank Feed-Thru PlatesThe Transformer Tank Feed-Thru Plates come in two sizes; one that allows up tosix fiber optic feed-thru connections and the other that has the capacity for twelvefeed-thru connections. Both Feed-Thru Plates can be ordered to be populatedwith as many feed-thru connections or plugs as required by the application. ThePlates are secured to the transformer tank on welded bolts and sealed with a




Six hole Transformer Tank Feed-Thru Plate Dimensions




Before the Feed-Thru Plate can be bolted into place on the transformer tank thefiber optic probes that are installed in the tank must be connected to the Feed-

Thru connectors located on the underside of the plate. Dress the fiber opticcables in such a fashion that once the plate is bolted in place, the cables will not

be strained nor should they be placed in a position to cause a dielectric hazard. Itshould be remembered that while fiber optic cables are more rugged than theywere years ago they still are not as forgiving as copper wire. Therefore careshould always be taken when dressing and securing fiber optic cables. The endsof the fiber optic probes are secured to the feed-thru connectors using STconnections.

Feed-Thru Connectors




should be maintained documenting the path from the probe to the Feed-ThruConnector to the fiber optic cable so that the user knows what temperature

parameters of the transformer he is measuring with what converter. Once all thefiber optic connections are made then secure the Cover to the Feed-Thru Plateusing the three mounting screws.

In some applications more Direct Temperature Fiber Optic Probes will beconnected to the Feed-Thru plate than will be measured with the 509 system. Inthese instances the customer can select which probes they would like to measure.The advantage of this is multiple probes could be installed during the heat runtests and the customer may pick and choose which ones to continue to monitor.




Fiber Optic Transmitters and the 509There are three styles of mechanical packaging for the Fiber Optic Transmitters;an all encompassing weather proof enclosure for the 509 and fiber opticconverters, an auxiliary weather proof enclosure for just the fiber optic




Auxiliary Enclosure Style

The auxiliary weather proof enclosure is approximately 8.5 by 10.5 by 6.5 inches

in size and designed to be back-mounted to any smooth surface. Four 0.31” by0.50” oval slots are provided for use with suitable fasteners to accomplish this.It is designed to house the fiber optic transmitters and optional heater in aseparate enclosure from the 509 itself. This packaging style has two advantages;




Bracket Mount

The third mechanical package for the fiber optic transmitters is designed to fit ina 19-inch rack. This package works in conjunction with the 509 Rack Mountunit. It would also be an option if the customer had a 509 panel mount unitwhere they were installing the 509 and the fiber optic transmitters in their owncontrol cabinet. The bracket is 4U high, approximately 5.0” deep and requiresfour screws to mount it in the control rack. Additional area behind theTemperature Monitor should be allotted for the wiring harness. See below for themounting centers and dimensions.




Universal Power Supply

The Universal Power Supply for the Fiber Optic Transmitter is DIN railmountable and should be located near the Fiber Optic Transmitters. The PowerSupply will accept an input power supply range of 85 to 264 VAC (50-60 Hz) or90 to 350 VDC. The output of the power supply is 24 VDC. The 24 VDC isthen wired to each Fiber Optic Transmitter as shown above. The Power Supplyis capable of powering 8 Fiber Optic Transmitters at the same time.

Current Input Module in the 509The Current Input Module needs to be configured to accept the 4-20 mA DCsignal from the Fiber Optic Transmitter. This will usually be done at the factoryunless this is an upgrade item. For the Fiber Optic Transmitter application the

jumpers on the Current Input Module should be set as follows:
