HYDRAN-M2 modular

Description

Overview
Based on field-proven technology, the new Hydran M2 adds
transformer mathematical models based on IEEE® and IEC®
standards to provide real-time information on the overall
performance of the transformer. This extends the monitoring
to more failure modes than by dissolved gas and moisture
monitoring alone.
When an unexpected failure of a transformer occurs, the
operational and economic impacts are substantial. Today,
many existing oil-insulated transformers used by electrical
utilities and other industries are approaching the end of
their design life and are exposed to significantly higher
probabilities of failures. Stringent regulations on the supply
of energy, the reduction of capital investment and operation
expense budgets, and the shortage of specialized personnel
are also increasing the need to extend the lifespan of these
transformers.
Key Benefits
Monitoring and performing real-time transformer modeling
can help reduce the risk of unexpected and sometimes
catastrophic failures. This also helps to avoid expensive
clean-up, replacement, and unplanned downtime. Early
detection of potential transformer problems is vital to the
lifespan extension of critical transformers and provides
significant business and operational benefits that will:
• Reduce inspection and maintenance costs by stretching out
the time between routine maintenance activities
• Reduce unplanned outages with continuous condition
monitoring and early detection of primary faults
• Provide greater lifespan confidence through the use of
on-line model computations providing real-time transformer
condition information
• Defer major replacement costs by optimizing the
transformer’s performance and extending its lifespan
