These instruments provide three-phase measurements of electrical quantities in power distribution systems, monitoring external events, operating external equipment via relay contacts, fast and long-term on-board recording of measured quantities, transient voltages measurements up to 2KV , fault recording of currents up to 10x nominal current (50A), harmonic analysis and disturbance recording. A high-contrast graphical LCD display with backlight allows easy local meter readings and servicing. Two serial communication ports (infrared and RS-232/RS-485), a USB port, Ethernet and a wireless GSM/GPRS modem allow local and remote automatic meter readings and setup though the supplemental communication software or user data acquisition software. The EM720 is especially designed for utility, industrial and commercial billing metering with high requirements to reliability of power quality monitoring and availability of the device. Highlights High Accuracy Revenue Meter IEC 62053-22 Accuracy Class 0.2S active and reactive energy polyphase static meter, with comprehensive TOU (Time-of-Use) to fit any utility tariff EN 50160 Power Quality Recorder A full-featured programmable power quality recorder provides EN 50160 compliance statistics and reports with IEC 61000-4-30 Class A accuracy Fast Transient Recorder An optional high-voltage fast transient recorder (EM720T) detects impulsive and low frequency oscillatory transient overvoltages with peaks up to 2kV and durations from 16/20 microseconds. Digital Fault Recorder An embedded fault recorder is capable of recording current faults up to 50 amps. Models The unit is available in two models: EM720 High accuracy revenue energy meter class 0.2S with Power Quality Analyzer according to EN50160 Standard, all the basic metering, control, and fault and event recording capabilities EM720T All the EM720 functionality plus transient recording capabilities
