Weezap

LV Supply Switch

Advanced protection and monitoring to support efficient LV network automation and management

Overview

Network Operators are facing increasingly complex demand patterns due to rising EV ownership and the adoption of low carbon technologies.

Weezap is an advanced vacuum circuit breaker-based switch and recloser. It allows DNOx to adjust supply arrangements to connected circuits remotely and dynamically, in line with changing load and supply conditions.

Weezap protects the network, opening the circuit breaker in overload and fault conditions, and providing automatic reclosing to facilitate quick supply recovery.​ ​It also collects information about fault activity, supporting fault location with Camlin Energy's SELF and MELF based techniques.

Weezap operates in conjunction with Camlin Energy's Gateway management device that can be used to trip, close and configure multiple Weezap units. It can also be integrated with DNOs’ own network management systems.

Benefits

Costly penalties icon

Avoids costly penalties

Weezap can be configured to restore supply automatically within the regulatory window to circuits that have lost power due to transient faults.

Security icon

Advanced network protection

The device can emulate characteristics of many different fuse models, automatically isolating supplies in the event of fault conditions.

Foresight icon

Visibility of network conditions

Full power quality measurement capabilities, allowing Network Controllers to assess network conditions and make strategic decisions.

Installation icon

Fast, easy installation

Quick and easy for field staff to retrofit safely on existing LV panels, with no need to replace the LV board and with minimal training requirements.

Cog process

Supports network automation

It can be remotely opened and closed to support dynamic network configuration.

Capability

  • Protects network by opening circuit breaker in overload and fault conditions
  • Can close and open circuit at LV substation either locally or remotely
  • 400A rating, certified to 35kA
  • Monitors current overloads and assesses duration and magnitude of overloads
  • Automatic network meshing and reconfiguration using embedded LV switches
  • Quick, easy retrofitting to existing LV panels with minimal training
  • Configuration settings allow local automated re-closing; or reclose control can be via Network Management System (NMS)
  • Communicates via SCADA for integration with existing network control architectures

Experience in action

Smart Street IRM: Optimisation of voltage levels through controllable switching devices

Camlin Energy acted as the key partner on the LCNI Tier 2 project Smart Street. This project proved that controllable switching devices, when integrated into the Network Management System (NMS), will allow the optimisation of voltage levels so that both customers’ appliances and the Electricity North West network run as efficiently as possible.

Following the successful innovation project, Electricity North West was awarded Innovation Roll-out Mechanism (IRM) funding for the targeted deployment of the Smart Street system to 180 distribution substations and the associated LV networks.

Optimisation software, part of the NMS, will use real time measurement and configuration data to manage the voltage and power flows on the Low Voltage (LV) network. Camlin Energy Weezap and Relink technology will be installed as part of the IRM to enable the optimisation software to autonomously manage the network.
