Furthermore, the protection relay supports sending and receiving of analog values using GOOSE messaging.
Section 2 1MRS758272 B REG615 overview The Ethernet ring solution supports the connection of up to 30 protection relays. If more than 30 protection relays are to be connected, it is recommended that the network is split into several rings with no more than 30 protection relays per ring. Each protection relay has a 50-μs store-and-forward delay, and to fulfil the performance requirements for fast horizontal communication, the ring size is limited to 30 protection relays.

Section 4 1MRS758272 B Requirements for measurement transformers Section 4 Requirements for measurement transformers Current transformers 4.1.1 Current transformer requirements for overcurrent protection For reliable and correct operation of the overcurrent protection, the CT has to be chosen carefully. The distortion of the secondary current of a saturated CT may endanger the operation, selectivity, and co-ordination of protection.
Section 4 1MRS758272 B Requirements for measurement transformers of the CT is distorted and it might have severe effects on the performance of the protection relay. In practise, the actual accuracy limit factor (F ) differs from the rated accuracy limit factor (F ) and is proportional to the ratio of the rated CT burden and the actual CT burden.
Section 4 1MRS758272 B Requirements for measurement transformers The adequate performance of the CT should be checked when the setting of the high set stage overcurrent protection is defined. The operate time delay caused by the CT saturation is typically small enough when the overcurrent setting is noticeably lower than F When defining the setting values for the low set stages, the saturation of the CT does not need to be taken into account and the start current setting is simply according to the...
