How to monitor remote installed transformers

1. RTMU CONCEPT Transformer Downtime can be as high as 20% of its life span, but recently monitoring transformers has taken a leap forward, as energy production sites seek solutions to lower maintenance costs . Appropriate Online Monitoring and diagnostics tools can held utilities to avoid unplanned failures, lower maintenance costs and extend useful transformer life Remote Transformer Monitoring Unit

2. Variables Monitored (Depending on Sensors Installed) Low/High Oil Level. Ambient/Winding temperature. Dissolved gas(Buchholz relay). Moisture in oil. Voltage, Current, Frequency, Power factor, Active & Apparent Power, etc . Fencing, Palm and Presence sensors. Remote operation of LBS/MCCB. Tap position and counter. On-line transformer diagnosis. Alarm points if needed.

3. Features 24VDC power supply. 4 DI/ 2 Do/ 2 AI standard supply with support up to 140 slave. GSM/GPRS/MODBUS communicable. High accuracy inbuilt RTC. Energy meter module as an added function. IP 65 Enclosure. Third party SCADA communicable. Advantages Reduced cost of maintenance. Increases transformer life span. Reduces chances of failures. Better Load management. 24x 7 access to operational data . Safety Secured from Blowing up or fire set in transformers. Monitoring and diagnosis for transformer in one or across multiple substation.

4. Features 4 DI/ 2 Do/ 2 AI standard supply with support up to 140 slave. GSM/GPRS/MODBUS communicable. High accuracy inbuilt RTC. IP 65 Enclosure. Energy meter module as an added function. Third party SCADA communicable.

5. Prevailing system Scheduled/ unscheduled maintenance. Man power involved at every maintenance, Human error investigated. High shutdown time for maintenance. Transformer Diagnosis available at only scheduled maintenance. Transformer not used for desired Life span. Greater chances of Fire set/ Breakdown. Only one time installation. High reliability due to no human interface. Almost zero shutdown time. 24 x 7 Transformer Diagnosis. Life span can be increased by installing RTMU. Fire set/ Breakdown chances decreases to a great extent. RTMU Innovation

6. Advantages Reduced cost of maintenance. Increases transformer life span. Reduces chances of failures. 24x 7 access to operational data. FO/wireless transmission as per requirement. Monitoring and diagnosis for transformer in one or across multiple substation.

7. Worthwhile for Utilities for Distribution transformers. Public sector providing power. PSU/Industries for their own transformers. Telecom Sector Industries. Oil and Mining industries. D.G. set manufacturers.
