The metering module alsocontains additional alarm setpoint andprotective relay functions (e.g. trip onoverfrequency or undervoltage, andalarm on reverse power or over amperedemand).The Metering Function PLUS has twoadditional wave form buffers andsupports harmonic analysis. With thetwo independent wave form buffers, thecurrent and voltage waveforms can berecorded, and allows detailed diagnostictriggering on events.If the Metering Function /MeteringFunction PLUS is ordered together withthe circuit breaker, it is already installedand ready for operation. As a retrofitpart, the metering function is simplyattached to the ETU and connected tothe CubicleBUS.For more information, please visit http://automation.usa.siemens.com/consultant/ or contact your local sales office.Siemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog13-51
