Vn rotated this angle points the semi plane that corresponds to a Reverse fault. Page Negative Sequence Current [0. Page Voltage Elements These units can also be set as inverse time curves.
Page In case this setpoint is enabled, the undervoltage element will be supervised by the breaker status. Otherwise, the element will operate independently of the breaker status. Page If the voltage input is set as the voltage measured by the 4 voltage transformer, then the metered value will be applied directly to the algorithm. This voltage can be taken through a grounding resistance, a high impedance grounding, a busbar voltage etc.
Page Power 52B type contact. The purpose of this setpoint is to avoid spurious trips caused by overloads after the breaker closure. Page This setpoint specifies the relay characteristic angle RCA for the directional power unit. This setpoint provides ability to respond to the function in any direction defined active forward power, active low forward power, etc. Page Stage 1 is used for alarm functions, while Stage 2 is used for tripping functions.
Events: This setpoint enables or disables the generation of events. All states in this function are affected by this setpoint. For more detail information go to section 5. Page [0. Page This is why F is not suitable for one and a half breaker configurations, or ring configurations where a transmission line or feeder has two breakers. Page Breaker Closing time Time : Estimated breaker Closing time, used for establishing the Closing order in a moment that allows the busbar and line voltages to be in phase.
Page In order to establish the closing permission signal, the first parameter used by the algorithm is the difference in magnitude between line and bus voltages, and afterwards, the angle difference and frequency slip are verified.
Page The main benefit is that after a considerable number of breaker operations, damage to internal connection elements, as well as to the chamber isolating element is drastically reduced, ensuring a longer life for the breaker, and reducing costly maintenance operations. Page is entered, the relay will produce a closing permission output, if it is guaranteed that the projected phasor will be within the limit marked by the setpoint, as shown in the following figure.

Page Mixed, 16 digital inputs: CC1…. CC16 Supervision: 8 digital inputs: CC1, Page This is not a grouped setpoint; there is a different setpoint for each input.
It is important to distinguish between this delay input time and the debounce time used for filtering undesired transients in the input signal. The Debounce time is always added to the delay input time. Figure 5—shows the types of signals associated to the different output configuration types. The second group, symmetrical and identical to the first, is formed by isolated voltage inputs FF16 and FF Using voltage detectors and current sensing, it is possible to implement several trip or close circuit supervision schemes, as well as protection of the unit output contact.
Page In order to assure a high isolation level between groups, the digital inputs for supervision have been located in a symmetrical basis. That is to optimize the isolation between groups that can be connected to different batteries, and therefore requiring a greater distance between circuits. Page This is a very frequent common case, and we must only wire the tripping circuit to terminals F35 and F36, leaving unused terminals F34, F15, F16, F17, F This latching or memory function is only guaranteed while the unit is powered.
