Transformer Monitoring device – Industrial with Energy Meter

IOTX-IE is a transformer monitoring device that needs to be installed near a transformer to measure its vital parameters such as RYB voltage and current, active power, apparent power, reactive power, active energy, apparent energy, reactive energy, PF from the energy meter installed on the transformer LV side, oil temperature, winding temperature, and protection relay status.

    IOTX-IE is a transformer monitoring device that needs to be installed near a transformer to measure its vital parameters such as RYB voltage and current, active power, apparent power, reactive power, active energy, apparent energy, reactive energy, PF from the energy meter installed on the transformer LV side, oil temperature, winding temperature, and protection relay status. Through the Motware platform, one can easily monitor the streaming parameters of the transformer. The Motware platform allows you to do predictive analysis of the dynamic copper loss, hot spot temperature, aging rate, and the residual life of the transformer. The device includes a GSM module to transmit the data to our cloud-based Motware application every 5 minutes, or as per the customer specified, the transfer rate depending on the set parameters. The data transferred is stored in the memory of the device. In the event of a network failure, it will transfer the data back to the cloud once the network is established. The device operates in mains and battery and comes with a geotagging facility.


    The IoTx-IE transformer monitoring device is a digital wireless and reliable solution, which is designed to monitor the distribution/transmission of the transformer’s parameters. It helps to overcome the limitations of the current conventional transformer monitoring systems by sending real-time data to the Motware IoT platform. It helps to review the transformer’s parameters at regular intervals to help in easy predictive analysis and preventive maintenance. Transformer losses can be acutely monitored and streamed over a GSM network that is connected to the cloud-based Motware application. The user can make productive and informative decisions based on the data captured in the transformer monitoring device. The Motware application provides alerts based on the limits applied on the streamed parameter values to avoid any damage.
