Fiber Optic Temperature Monitoring System for Transformers

Neoptix, a company specialized in fiber optic temperature monitoring, introduces today the T/Guard Link, the latest addition to its well-known T/Guard product family for effectively monitoring transformer hot spots.

The T/Guard Link is specially designed for small and medium size dry-type or oil-filled power transformers. Its small body allows an easy and effective installation into any size of transformer control cabinet. The T/Guard Link can also be ordered with a NEMA-4 protective enclosure for direct stand-alone mounting on the transformer tank wall. The T/Guard Link is a cost-oriented system that has all the features required for integration into a substation SCADA or control system. It is available with one to eight optical channels and can be ordered with the popular communication links such as serial RS-232, RS-485, MODBUS, DNP 3.0 or Ethernet serial bridge. The T/Guard Link also provides a 4-20 mA analog output for each channel.

"The new T/Guard Link is the perfect add-on to any small and medium-size transformers as users can finally get a clear picture of the transformer hot spots at a reasonable cost. The T/Guard Link represents a new generation of transformer hot spot monitors which will allow user to get critical information leading to immediate and sound decisions about the transformer loading parameters" says Mr. Jeff Meilleur, President of Neoptix. "We believe that users will immediately see the payback inherent to this cost-oriented optical monitoring system" adds Meilleur.

T/Guard Link components have been specifically selected for long-term performance, including the light source that has an MTBF of over 300 years of use, which is far superior to the expected life of the transformer. The T/Guard Link complies with all requirements, such as vibration, stress, electrical susceptibility and conductivity, for permanent and trouble-free installation on the side of a transformer. The T/Guard Link is compatible with all Neoptix fiber optic temperature probes and sensors, including the T2 model for transformer hot spot monitoring.
