ELECTRICITY METERING (a.c.) - TARIFF AND LOAD CONTROL - PART 21: PARTICULAR REQUIREMENTS FOR TIME SWITCHES (SECOND REVISION) (IEC 62054-21:2004, MOD)
MS 62054-21:2009
Status : 2nd Revision
Format : PDF

This Malaysian Standard specifies particular requirements for the type test of newly manufactured indoor time switches with operation reserve that are used to control electrical loads, multi-tariff re ....Read more gisters and maximum demand devices of electricity metering equipment. 

The time switch keeps the real time, it may keep the date, it may be capable of handling leap years, it may support daylight saving, i.e. it modifies the deviation of local time to GMT according to the relevant regulations. The time switch may have a synchronization capability. The time switch also holds a schedule of switching actions, which may be specified in terms of time, day of the week, date within a month or a year. The time switch controls the output elements depending on the time and the schedule of switching actions stored.

This standard gives no requirements for constructional details internal to the time switch. In the case where time switch functionality is integrated into multifunction electricity mete Close
