| Objectives | The project proposes to test the feasibility of a technical alternative and lower cost fault locating device. This will be achieved by WPD providing a real-world testing opportunity, and by the manufacturer using this opportunity to demonstrate (and tune at their cost) the fault locating devices operation.The project proposes to install substation monitors capable of identifying and locating distance to cable arcfaults. Each monitor consists of Rogowski Coil based phase-current sensors (for up to five LV feeders) together with voltage taps, connected to a Metrology and Communications Unit (MCU) which processes the sensor data and generates and logs substation loading and condition parameters.Each monitor will capture and retain voltage and current waveforms from the monitored LV feeders when preset triggers are activated (e.g. rate of change of voltage or phase current). The captured waveforms will be forwarded via a GPRS/mobile data connection to a processing data centre where inductance and resistance values for the faulting network will be estimated. The estimated value of inductance will then be used to establish a distance to fault estimate. The project will follow a two phase approach.In Phase One, monitors with the suppliers existing fault location capability will be installed, and data will be analysed by the supplier. This Phase One data will primarily be used to confirm operating parameters forimproved data capture hardware that the supplier has also already designed. This improved fault locationhardware and capability will then be deployed and tested in Phase Two of the project.Phase Two will then seek to demonstrate optimised fault location data for monitored feeders to thedistribution business. 1. Test the feasibility of a technical alternative and lower cost fault locating device.2. Derive insight into the potential to more widely and cost-effectively deploy such monitoring equipment to feeders showing early indications damage (e.g. transient fuse operations). | |
| Abstract | The project will demonstrate an alternative approach to identifying the location of transient LV (pecking) faultswhile the cable is in normal service, before they have developed to a permanent fault requiring immediatelocation and repair. The project will achieve this by installing 26 newly developed monitoring devices atselected sites in the East Midlands region, and assessing the effectiveness of the associated distance to fault calculation results on real networks in normal service. | |
