ECLIPSE DFWT Install and Application Guide
Title:
Written By: T. Williams & J. Mundackal
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.
This application guide will discuss in detail:
• Theory of Operation
• New Transformer Application
• Retrofit Application
• Fiber Removal
• ECLIPSE Programming
• Testing

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. - Page 14 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.

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.
