Power Quality Monitoring

▼▼Chapter 3The H series electronic energy metersAreas of applicationElectrical energy meters are used to collect effective energy data.Their standard area of application is in the field of energy managementfor cost centre analysis. A pulse output is available in order toavoid time-consuming manual readings on site.The effective pulses can be connected via pulse output to e.g.DDC, PLC, SCADA systems or the data collection instrumentProData ® .ApplicationsThe electronic energy meters of the H series are suitable for themeasurement of effective energy. Measurement is laid out for a 1-and 3-phase system with a voltage of L-N 207-253VAC. The currentinputs are designed for direct connection or for measurementthrough a current transformer. The meter is installed on a DINrail.The accuracy level of the meter is class 1.Main featuresDirect measurement up to 65A or through a current transformer Class 1S0 interface pulse outputInstallation on 35mm DIN rail7 digit LCD display“In operation” modeData collection and displayAll meters store the energy values in non-volatile memories.The diagram on the right side shows the call-up possibilities for thevarious data.Display test –all segmentsactivatedCurrent transformerratio (only for CTmeters)Currentenergy value= Briefly flashes on and offwith an external light97
