82 new LN Class, control measuring functionCreated: 16 Mar 2005 Status: In Force (green) Part: Part 7-4 (2003) Links: Page: Clause: 5.10 Paragraph: Category: Issue for edition 2 of this part Issue In relating the automatic control functions, it is commonly used to issue single information as “Bus voltage presence”, “line voltage ausence” and so on. This information is usually obtained as the output of a analogue comparator programmed within the IED. Then, we find usefull to standardiza a new LN Class, control measuring function, that can be used for busvoltage, line current etc…with general parameters as CF DAI for deadband, lcomparator levels and adjustable time delay, because this information is quite common in all SAS.
Proposal Create a new logical node MCXL class as it is shown in the Figure 1. In that figure one can be can seen the LN performance as well as related attributes.
