WAGO 750-495/000-002 3-phase PoM690/ R.C. content_copy

3-phase power measurement terminal, 690 V AC / Rogowski coils
The 3-phase power measurement module 750-495 permits the measurement of the electrical data of a three phase supply network. The voltage is measured via the connection of the network to the terminal points L1, L2, L3 and N. The current of the three phases will be via current transformers to the IL1, IL2, IL3 and IN (two terminal points +, -) fed. The preprocessing of the 3-phase power measurement module provides all measured variables such as reactive / apparent / active power, energy consumption, power factor, phase angle, frequency and over- / undervoltage and overcurrent / undercurrent directly in the process image is available without spending high computing power on the controller presuppose. These extensive measures and harmonic analysis up to the 41st harmonic thus enable to conduct a comprehensive network analysis via the fieldbus. On the basis of measured quantities delivered, the plant operator will be able to supply a drive or a machine is optimized to regulate and protect the system from damage or outages. The additional measurement of the current in the neutral conductor can help detect insulation faults or avoid. The 4-quadrant display gives information on the type of load (inductive, capacitive) and whether it is an energy consumer or producer. Number of inputs: 7 (3 voltage measurement inputs, 4 differential current measurement inputs) waveform: any periodic signals (under into account the cut-off frequencies) Calculated variables: phase voltage, services, energy, power factor, frequency, harmonic analysis (up to 41 harmonics) THD Type: 750-495 / 000-002 Quantity: 1 ST.
