Description
The CKEL-27 on-load disconnector has solid insulation and an innovative fault indicator system accompanied by the control system that allows the implementation of smart grids, as backup elements or sectionalizing faulty areas in distribution systems, being programmed logically with the reclosers either using schemes coordinated with the protections or after the protections work from automatic, semi-automatic or manual controls from the SCADA system.
Disconnectors under load, also known as LBS (Load Breaker Switch) or DBC (Disconnect Switches Under Load) allow maneuvers to be carried out in electrical systems even when the system is energized and under load.These devices allow carrying out maintenance and replacement maneuvers which can be operated locally by means of the control or pole or remotely since it allows integration into SCADA systems through communication protocols such as DNP 3.0, IEC 60870-5-101 / 104 or Modbus.
