LN: Supervision of operating mechanism Name: SOPM
This LN is used for supervision of operating mechanism for switches. It is used to assess the condition of the operating mechanism and can be used to indicate a possible malfunction in the future.
Today, different technologies for operating mechanisms are available. Typically operating mechanisms for circuit breakers contain an energy storage to provide the required switching energy within a short time. Examples for today’s storage medias are springs or compressed gas. To operate the switch, the energy is transferred by means of a mechanical or hydraulical linkage. A charger motor is used to compensate energy losses due to leakages or to recharge the storage after a switch operation.
|
The proposed attributes cover the status of the relevant components both of the hydraulic system and the spring system. Depending on the used technology, some of the attributes are not applicable. This LN can also be used for simple operating mechanisms that are directly driven by a motor.SOPM class |

LN: Circuit switch supervision Name: SSWI
This LN is used for supervision of all switches, such as disconnectors, earthing switches, etc. except circuit breakers. It is used to assess the condition of the switch and is closely related to LN SOPM. Most attributes are used to supervise the operation time of the switch and contact movement. Deviations from nominal values can be used to indicate a possible malfunction of the switch in the future. Abrasion of parts gives an indication when to maintain the switch. For the special requirements of a circuit breaker, the abrasion, etc. is defined in LN SCBR. The supervision SSWI is per phase.
