Transformer Monitoring System

Transformer Monitoring System (TMS) is primarily health monitoring of the equipment that can acquire, process, analyze & communicates the critical parameters to centralize Data Center for analysis and visualization of wide spread Distribution Transformers and Power Transformer in Electrical Network

Transformer Monitoring System increases the reliability of distribution network. Not only the conventional technical data, such as current, voltage, etc., but also other critical information such as moisture, oil temperature, oil level etc. of transformers, are required by the operators to ensure reliable power delivery and to assist the day-to-day decision making activities.

Monitoring condition of Insulation Degradation:

On line Dissolved gas Analysis, Hot spot, and Tan delta of bushing for Power Transformer helps to monitor the health of transformer and more important loading of the transformer can be accurately controlled. Insulation integrity is vital to your transformer's operation. Moisture buildup and transformer overheating are two conditions which may lead to irreversible insulation degradation. NI cRIO accurately monitors the evolution of both moisture and carbon monoxide, allowing optimal scheduling of additional insulation integrity tests such as Dissolved Gas Analysis (DGA) and Furan testing.

Hydrogen Monitoring

Even at the earliest stages of fault development, both thermal and electrical stresses on  transformer oil will generate dissolved hydrogen. In addition, the highly mobile hydrogen is quickly distributed throughout the oil, providing an early and reliable fault signature.

NI cRIO excels at timely and accurate low-level  hydrogen measurements.  When installed on your critical transformers, NI cRIO provides the earliest possible fault detection, and allows  accurate real-time monitoring of subsequent fault evolution. 

This  unique hydrogen measurement  technology requires no calibration and is  field-proven          to prevent equipment failure and  extend transformer life.

Carbon Monoxide Monitoring:

Carbon monoxide is a by-product of cellulose  degradation. Although generated in all  transformers under normal operating conditions, anomalous amounts of carbon monoxide may be generated when localized cellulose  overheating occurs. NI cRIO provides a  dependable measurement of the CO baseline, and will alarm on a sudden increase of CO  concentration. Timely follow-up with  laboratory DGA and furan analysis will enable  early detection of accelerated aging of solid  insulation, before significant       and        irreversible         damage is incurred.

The TMS collects data from remote transformers with communication interface (GPRS/CDMA) to provide daily usage, total usage, real time data and long-term data management, automatic report generation, energy accounting & graphical representation of transformer on GIS at centralized Data Center
