B & W Technologies Q2Q Phase to Phase Fault Locator
The device is intended for use on energised low-voltage networks and supports fault-finding activities by helping operators determine the likely position of a fault quickly and systematically.
- Phase to phase type faults (welds) cause unwanted problems on the low voltage electricity network.
- Q2Q has been developed by B&W Technologies to identify the location of faults on electricity distribution networks where two phases have become welded together.
- It is an easy to use phase to phase fault locator that has been validated by SSEN as the first step towards minimising disruption to customers after a fault.
Q2Q Key Features:
- Supports accurate fault location on low-voltage electricity distribution networks.
- Designed for use on energised networks, reducing the need for unnecessary interruption.
- Calculates the estimated distance to fault using on-load testing data.
- Provides an estimated geographical fault location after cable data is entered.
- Offers a guided user experience through step-by-step on-screen instructions.
- Helps improve efficiency during fault investigation activities.
How It Works
Connection to the Network: The device connects directly to the energised low-voltage network.Measurement Process: It operates by taking electrical measurements while switching loads in and out of the network.Distance Calculation: Data obtained from on-load testing is used to calculate the estimated distance to the fault location.Location Estimation: The operator then inputs cable types and cable lengths via the touchscreen interface, allowing the device to provide an estimated geographical location of the fault.
