E1, E2, and E3 are designed to interface to a microprocessor. 2 EQUATIONS OF HOMOGENEOUS FLOW 220 9. This booklet, NorthWestern Energy Electric Service Requirements and Guidelines, was prepared to aid employees, contractors, electricians, commercial customers, and any other electric customers who need detailed information in establishing electric service for new. 1 Measurement 14 3. use the 3 resistances measured in part B. The meter is for LV or HV three-phase user. The flux φse is produced by the load current I and Φse is in the direction of I (see Fig. The current demo board firmware has the capability to measure Neutral Currents. - The meter has advanced data and tamper recording capabilities and is provided with communication ports. The main functions of the energy meter are: Measuring voltage, current, active and reactive power, as well as active and reactive energy Can be used as a bidirectional meter for measuring grid feed -in and load Multi -tariff measurement. The functionality of this meter is suitable for smaller consumers, i. Complete the table concerning the load characteristics of the service. SEVEN-TERMINAL, 200 AMP, THREE-PHASE METER SOCKET. Apparatus: - One single phase energy meter, one single phase load, Stop watch and connecting wires. over frequency, under frequency, over total voltage harmonic distortion, over total current harmonic distortion, phase lose, meter restore factory, phase sequence reversal, over DUI, over EU * Data log: Phase voltage, line voltage, current, natural current, power factor, displacement power factor, total active power, total reactive power, total apparent power, positive active energy, reversed active. ENERGY 10MANAGEMENT Diris® A THREE - PHASE MULTIFUNCTION METERS Energy Management and Network analysing meters. These diagrams show the use of single-phase, directly connected wattmeters. Manufacturer of Digital Panel Meters - AVF Meter, Energy Meter, VIF Meter and Voltmeter offered by Darade Corporation, Pune, Maharashtra. Phasor diagrams for the meter voltages and currents, assuming unity power factor for a balanced three phase load, with A-B-C phase sequence on top and C-B-A phase sequence on the bottom.
