Written By: T. Williams & J. Mundackal 04/27/2020 Application Summary The ECLIPSE is capable of providing Direct Fiber Winding Temperature using enhanced Rare-Earth tipped probes that utilize blue LED technology or using legacy phosphor tipped probes using red LED technology. The ECLIPSE with DFWT may be applied on new transformers and can be used to replace legacy fiber probe Monitors using red LED legacy phosphor fiber optic probes.
The ECLIPSE provides a pulse of light that excites the Rare-Earth material coating where the decay rate is a function of temperature. The ECLIPSE uses the decay rate to determine the temperature within ± 2 C Page 3 of 21...
Advanced Power Technologies’ enhanced blue LED phosphor technology. DFWT allows for the direct measurement of the winding hot spot temperature rather than traditional methods such as simulated winding hot spot temperature using a heated thermowell or calculated winding temperature. The advantages of the DFWT include: faster response of...

The contamination results in attenuation of the light transmitted or reflected. Apply clean dry air (Air duster) to the ports to remove the foreign particles. Do not use compressed air. Page 10 of 21 AG010 ECLIPSE DFWT Install and Application Guide Rev 20200427...
Note 2: The dust caps should be left on both ends of the connectors during the installation process, until the connectors are connected to flange plate and ECLIPSE. Figure 3.8 ECLIPSE back panel with 8 direct fiber channels Page 11 of 21 AG010 ECLIPSE DFWT Install and Application Guide...
Note 1: The dust caps must be left on the ECLIPSE fiber channels until the fiber extensions are connected properly. This keeps the dust, dirt and moisture away from the fiber channels. Note 2: If the user leaves the fiber channels open it may...
40 and 140 ˚C. In addition, there are fiber optic temperature probe alarm points (ALFPROBE1 – ALFPROBE8), one per fiber probe channel. These alarms pick up when the ECLIPSE detects a problem with one of the fiber probes, fiber probe extensions, and/or fiber measurement channels, and the ECLIPSE is unable to acquire temperature correctly on that channel.

NOTE The ECLIPSE allows a maximum of one TOP OIL, one BACKUP TOP OIL, and two LTC DIFF / LTC TANK probes. There is no limit on DISABLED/GENERIC probes. If BACKUP TOP OIL probe is defined, the ECLIPSE will automatically switch to BACKUP TOP OIL probe for the top oil temperature if the TOP OIL probe fails.
When the temperature drops below the pickup setting, the set point picks up, and when it rises above the dropout, it will drop out. Page 15 of 21 AG010 ECLIPSE DFWT Install and Application Guide Rev 20200427...

NOTE If ALFPROBEn alarm picks up, consider swapping the fiber on that channel with the fiber from another working channel at the back of the ECLIPSE as a troubleshooting starting point. If the alarm goes away when another working fiber is connected to that channel, then the problem is not with the fiber channel but with the fiber probe and/or fiber extension on that channel.
7 Testing For testing fiber channels, a connection will need to be made to the ECLIPSE through the front panel-mounted DB-9 connector with the following port settings: • Baud Rate: 19200 bits per second • One start bit • 8 bits of data •...
