4.2 Electrical parameter query
Environmental monitoring In the main wiring diagram, you can directly view all electrical parameters of the circuit, including PTC resistance, three-phase current, three-phase voltage, three-phase total active power, total reactive power, total power factor, active energy, etc.
4.3 Curve query
Motor monitoring In the curve query interface, you can directly view various data history curves, including three-phase current, three-phase voltage, active power, reactive power, power factor, resistance value and other curves.
4.4 Operation Report
Query the operating parameters of each motor equipment at a specified time. The electrical parameter information displayed in the report should include: current of each phase, voltage of three phases, power factor, total active power, total reactive power, forward active energy, etc.
The system has the function of regular meter reading and summary statistics. Users can freely inquire about the power consumption of each motor in any time period since the normal operation of the system, that is, the statistical analysis report of the power consumption of the motor and the power consumption of each branch circuit.
