Section 2 1MRS756378 S REF615 overview The protection relay stores 2048 audit trail events to the nonvolatile audit trail. Additionally, 1024 process events are stored in a nonvolatile event list. Both the audit trail and event list work according to the FIFO principle. Nonvolatile memory is based on a memory type which does not need battery backup nor regular component change to maintain the memory storage.
Section 2 1MRS756378 S REF615 overview PCM600. The audit trail cannot be reset, but PCM600 Event Viewer can filter data. Audit trail events can be configured to be visible also in LHMI/WHMI Event list together with process related events. To expose the audit trail events through Event list, define the Authority logging level parameter via Configuration/ Authorization/Security.
Section 2 1MRS756378 S REF615 overview communication protocol is supported by using the protocol converter SPA-ZC 302. Operational information and controls are available through these protocols. However, some communication functionality, for example, horizontal communication between the protection relays, is only enabled by the IEC 61850 communication protocol. The IEC 61850 communication implementation supports all monitoring and control functions.

Section 2 1MRS756378 S REF615 overview IEC 62439-3:2012 cancels and replaces the first edition published in 2010. These standard versions are also referred to as IEC 62439-3 Edition 1 and IEC 62439-3 Edition 2. The protection relay supports IEC 62439-3:2012 and it is not compatible with IEC 62439-3:2010. Each PRP node, called a doubly attached node with PRP (DAN), is attached to two independent LANs operated in parallel.
Section 2 1MRS756378 S REF615 overview • Via an external redundancy box (RedBox) or a switch capable of connecting to PRP and normal networks • By connecting the node directly to LAN A or LAN B as SAN • By connecting the node to the protection relay's interlink port HSR applies the PRP principle of parallel operation to a single ring, treating the two directions as two virtual LANs.

Section 4 1MRS756378 S Requirements for measurement transformers Section 4 Requirements for measurement transformers Current transformers 4.1.1 Current transformer requirements for non-directional 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 1MRS756378 S 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 1MRS756378 S 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...
