and monitoring of different types of bays in power networks. The IED is especially suitable for applications in control systems with distributed control IEDs in all bays with high demands on reliability. The IED can be used up to the highest voltage levels. It is suitable for the control of all appara ...

directional independently for each of the steps. A second harmonic blocking can be set individually for each step. EF4PTOC can be used as main protection for phase-to-earth faults. EF4PTOC can also be used to provide a system back-up for example, in the case of the primary protection being out of service due to communic ...

initiated to allow use with single phase tripping applications. For the three-phase version of CCRBRF the current criteria can be set to operate only if two out of four for example, two phases or one phase plus the residual current start. This gives a higher security to the back-up trip command. CCRBRF function can be pro ...

ROV2PTOV calculates the residual voltage from the three-phase voltage input transformers or from a single-phase voltage input transformer fed from an open delta or neutral point voltage transformer. ROV2PTOV has two voltage steps, each with inverse or definite time delayed. Voltage differential protection VDCPTOV A vo ...

remain and extremely high voltages will stress the secondary circuit. Current circuit supervision (CCSRDIF) compares the residual current from a three phase set of current transformer cores with the neutral point current on a separate input taken from another set of cores on the current transformer. A detection of ...
