INNOVATION Calls

Current sensing devices

The latest in a series of calls for innovation seeks potential solutions to a problem area identified by a number of Distribution Network Operators (DNOs).

 

The drive for greater visibility of the low voltage network has led to the development of low cost monitoring devices.  However, the rogowski coils and current transformer devices currently being used for monitoring the feeder currents are expensive.  Our DNO partners are looking for alternative manufacturers or alternative sensing devices that can significantly lower the cost of current measurement on low voltage feeders.  These solutions must suitable for installing in three-phase feeder cable systems at both indoor and outdoor locations.

 

A second area of interest for this call relates to the problems associated with the multiple cable connections required from the sensing devices to the local monitoring units. A six feeder installation requires 18 current sensors. The management of these 18  cables can cause a significant hazard within the feeder pillars and substations.  Our DNO partners are looking for potential solutions to this problem including the use of wirelss technology to transmit the current measurements from the sensors to the measurement units. The devices will be required to harvest the appropriate power from the network.

 

Desired outputs from this call include:

 

  • An alternative early-stage technology, or;
  • A market-ready product.

 

The solution should benefit the DNOs by giving a flexible current sensing device that will make installation, usage and replacement easier for field operatives.
