New-Generation Monitor Expands Benefits of Monitoring to Distribution Transformers

BPL Global, Ltd. has announced a transformer monitoring solution with the delivery of the Serveron TM1 On-line Transformer Monitor for distribution and other power transformers in the grid.

The TM1 is already deployed with utility customers in the United States and internationally. The benefits of on-line condition monitoring can be realized across the entire power transformer fleet. Dissolved gas analysis is the single best indicator of transformer health. BPLG has delivered DGA-based on-line transformer monitoring on a global basis with a proven business case supporting transformer failure avoidance, reduced maintenance costs and deferred capital expenditures.

Hydrogen gas buildup in transformer oil is an early indicator of incipient transformer faults. The Serveron TM1 continuously monitors hydrogen (H2) PPM Levels using DGA and can be programmed to alarm based on PPM Levels and/or Rate of Change (ROC), warning operators of potentially disruptive transformer faults and pending failures. Optional moisture-in-oil measurement is also available.

Because DGA monitors should be as reliable as transformers, BPLG has solved the major reliability issues with previous generation single gas monitors causing poor measurement accuracy and high levels of maintenance and replacement. This patented design has no membrane and does not require sensor replacement, consumables, or scheduled maintenance. The TM1 significantly reduces the cost of ownership for electric utilities and improves the accuracy of hydrogen gas monitoring.
