Monitoring makes the difference

An overview of transformer monitoring systems market in India. It also elucidates the concept of remote monitoring catching up in India

With the advent of technology at your door step, people are looking for more and more automation. Smart technology is helping the human community to access data in a most easy fashion. Today the complete process of information system is data base oriented. Scientists are continuously working for devices which can convert information to intelligence. Transformer being a heart of power transmission network also does generate lot of important data which can be amalgamated to conclude on the healthiness of a transformer. These data are real time and dynamic. On pure data analysis system software can raise alarm along with caution notice and hints for a prospective fault or even can arrest data which can be helpful for taking proper action in time to save from a power outage. “The monitoring system is nothing but a SCADA based software which continuously analyses the current value with set parameters to check the health of winding and oil. The system remains connected to a nitrogen purging system which when switched by the SCADA output can protect the transformer from overheating and burning. Thus not only it helps the power system to get isolated from a probable fire hazard but also safeguard the maintenance staff or passersby from sever accident which may unlikely go up to loss of life,” explained Sanjib Mitra, Vice President – Sales & Marketing, Transformer & Compact Substations, Electrotherm (India) Ltd. He assures that the system is highly reliable and has a watchdog connectivity and quite helpful for substations and industries.

Transformer monitoring systems is an advanced tool that engineers and managers now have to maintain and monitor their assets remotely. Transformer monitoring therefore as a domain is quite diverse based on its application and/or the need of the user. Whereas, for generation and transmission utilities, including steel furnaces or other critical to operation transformer; the prime goal is to trend and monitor any trace of incipient fault within the system – and this essentially is the key objective of the monitoring systems. “Advancements in techniques for determination of several parameters like partial discharge, dissolved gasses, acoustic emission etc are now being introduced in the market. Whereas, all such systems demands a very high investment; the return essentially is not meeting the expectations,” said Divyansh Kohli, CEO and Executive Director, NDL Power Limited.
