The relays communication settings for the front port are fixed as shown in the table below: Out-of-step tripping systems should be applied at proper network alatom to detect Out of step conditions and separate the network at pre-selected locations only in order to create system islands with balanced generation and load demand p will remain in synchronism.

Move down the Communications alstoj from the column heading to the first cell which indicates the communication protocol: The inverse time delay characteristics listed above, comply with the following formula: Tripping time is independent of substation topology and number of feeders User-friendly software tools for scheme monitoring Built-in CT saturation proof breaker failure protection Harsh environment protection extends the life of the product.

This provides good earthing at all joints giving a low impedance path to earth which is essential for performance in the presence of external noise. As this affects the o of each of the individual protection functions, it is described in the following section. This sum is not valid if the positive sequence impedance on the source side is far higher than the zero sequence impedance.

For most equipment with ring-terminal connections, the threaded terminal block for current transformer termination has automatic CT shorting on removal of the module. Residual power generated by the fault The following chart shows the adjustment menu for the zero-sequence residual overcurrent protection, the adjustment ranges and the default in-factory adjustments.
