All settings with an index higher than 1 up to MaxCyc will appear if MaxCyc is higher than 1.

For the number of actual permitted (used) cycles holds: UseCyc < MaxCyc.

  1. LN: Synchronism-check Name: RSYN

For a description of this LN, see IEC 61850-5. The voltage phasor difference from both sides of an open breaker is calculated and compared with predefined switching conditions (synchrocheck). Included is the case that one side is dead (example: energising a dead line).

  1. LN: Circuit breaker supervision Name: SCBR

For a description of this LN, see IEC 61850-5. This LN is used for supervision of circuit breakers. Operating a breaker and especially tripping a short circuit causes always some abrasion (or erosion) of the breaker contacts. The supervision is per phase since each phase has its own contact.

  1. LN: Insulation medium supervision (gas) Name: SIMG

For a general description of this LN, see IEC 61850-5. Insulation medium is gas, for example SF6 in gas isolated devices. For other measuring objects related to the same IED, a new instance of SIMG may be used. If the new measuring point(s) is/are related to a new IED, in this new IED a new instance of SIMG shall be used.

  1. LN: Insulation medium supervision (liquid) Name: SIML

For a description of this LN, see IEC 61850-5. The insulation medium is a liquid such as oil, like that used for example for some transformers and tap changers. For other measuring objects related to the same 1ED, a new instance of SIML may be used. If the new measuring point(s) is/are related to a new IED a new instance of SIML shall be used.
