Section 2 1MRS758755 A REC615 and RER615 overview Web HMI The WHMI allows secure access to the protection relay via a Web browser. When the Secure Communication parameter in the protection relay is activated, the Web server is forced to take a secured (HTTPS) connection to WHMI using TLS encryption.The WHMI is verified with Internet Explorer 8.0, 9.0, 10.0 and 11.0.
Section 2 1MRS758755 A REC615 and RER615 overview • Locally by connecting the laptop to the protection relay via the front communication port. • Remotely over LAN/WAN.

Section 2 1MRS758755 A REC615 and RER615 overview Audit trail is a chronological record of system activities that allows the reconstruction and examination of the sequence of system and security-related events and changes in the protection relay. Both audit trail events and process related events can be examined and analyzed in a consistent method with the help of Event List in LHMI and WHMI and Event Viewer in PCM600.
Page 43
Section 2 1MRS758755 A REC615 and RER615 overview PCM600 Event Viewer can be used to view the audit trail events and process related events. Audit trail events are visible through dedicated Security events view. Since only the administrator has the right to read audit trail, authorization must be used in PCM600.
Section 2 1MRS758755 A REC615 and RER615 overview Communication 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 12 1MRS758755 A Requirements for measurement transformers Section 12 Requirements for measurement transformers 12.1 Current transformers 12.1.1 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 12 1MRS758755 A 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 12 1MRS758755 A 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...
