Background

Being not costly distribution transformers, utility companies don’t care that big number of outage potentials. Losing each distribution transformer normally at the pick time will reduce total revenue as well as customer satisfaction while cost-effective monitoring of such transformers provides live tracking to prevent any transformer failure.

Solution Overview

Hexing' Transformer Monitoring System (TMS) is designed based on state-of-the-art multi-functional gateway which accurately measures electrical parameters of transformer' LV side, manages belonging smart PLC or RF residential meters (as a DCU) and monitor transformer' oil or even control relevant feeder/transformer ( up to 800A).

This advanced TMS unit has 2 types for the cases that utility wants to monitor the transformer and manage smart meters or monitor transformer, manage smart meters with extra ability of remote switching. Basic unit measures secondary side of transformer via portable Rogowski CTs and advanced type does same measurement but via normal split-core CTs installed in the box. Collected load, network and oil data will be securely transferred to the utility over GPRS/3G/4G or even Ethernet cable.

Except asset management that is the main concern of Hexing TMS, there are other applications like peak shaving, loss monitoring (a key tool of ATC&C system) and Feeder monitoring, all to optimize smart grid structure.
