4G DTMU

CMSGP is a well known 4G DTMU manufacturer in India. We have been in the industry since the last two decades and have hands-on experience in designing the most efficient 4G distribution transformer monitoring units.

Distribution transformers are used in the electrical power distribution system to step down voltage levels to a low voltage level for domestic and industrial purposes. The power industry is deploying monitoring systems to enhance performance, safeguard their equipment like smart grid deployment, substation monitoring, etc. These monitoring units enable real-time monitoring of power consumption, failures, etc. and help in detecting potential problems and improving performance. This DTMU helps in enhancing power efficiency and gives quick response in case of sudden breakdowns.

Creative MicroSystems being sophisticated 4G DTMU manufacturers offer smart energy metering solutions. Our 4G network routers enable fast and easy data transmission for real-time monitoring of substation’s performance. To know more about our products’ features and price reach us.

  • Enhances the life of transformer assets
  • Individual phase transformer loading
  • Temperature monitoring of transformer
  • Reporting of power quality values of the transformer
  • Real-time alarms for power outage, tampering and power quality threshold exceedances
  • Data can be used for carrying out Energy Audit, Load Survey and Fault Analysis
  • Real-time dashboard reporting overall transformer and communication status
  • Reduce cost of scheduled and unscheduled maintenance
  • Enables the utility to carry out better load management as it provides accurate real-time information on transformer loading
  • Can be used to ascertain theft detection and localisation based on behavioural patterns of the transformer
  • Decrease outage duration - detect transformer or outgoing LV feeder outages or problems and send outage events to the central system
  • Comprehensive reporting of monitored parameters in a consolidated manner for analysis. Overcapacity, thresholdcrossing, etc are highlighted in the reports
  • Instantaneous alerts to Operator as well as field personnel describing alert incident e.g. oil level low threshold reached,monitored parameter crossing upper/lower threshold, etc.
