The effective power table refers to the power measurement instrument that is used to measure the power output or consumed by electrical appliances. Generally, electrical parameters such as voltage, current, and power factor can also be measured.Powerful power refers to the average value of the integral power in one cycle. Therefore, the power power is also called the average power.
Powerful power table wiring
Powerful power table characteristics: Direct validity measurement: voltage/current/power/power factor/frequency/electrical/non -effective power, etc.The current and voltage variable ratio can be set freely.There are three -way alarm output, which is suitable for various power control.With a configurable 4-20mA transmission output.Power voltage AC90-260V50Hz/60Hz.With the RS-485 communication port, you can choose the MODBUSRTU protocol.It can be used for automatic control of distribution power projects such as power systems, factories, and building automation.Such as: three -phase, voltage/current/power, comprehensive display control or up to up to six -way voltage/current display control.
Powerful power table model
PL34 three -phase and four -line, unbalanced overload, dial 240 ° PQ34 three -phase and four -line, unbalanced overload, dial 90 °
Principles of functional power table
Powerful power table ---- indicate the instantaneous value of the effective power consumed by the current device with a pointer.Meeting P has a skill and electrical table ---- Direction disk indicates the cumulative value of the current equipment consumed.Testing W (w = pt) The power table is measured by the power table. It is different from the value of the total power obtained on the load on the load.The value, this ratio is called the power factor. The total power measured by the V table and A table is measured by the power -based power table.For example, you can use a few UF capacitors in the 220V circuit (more than 300V to resist voltage). The power value measured by the power table should be basically zero, but the total power measured by the V table and A table cannot be the total power measured by the V table and A.Zero, because there is a current flow and voltage, but because the portion deviation capacitor does not consume power, the power is zero, and the remaining is non -functional power, so the meter at home (with a meritorious meter) should not bechange.(If the slow rotation is because the line resistance consumes power), the power factor can be obtained with the total power ratio of the power ratio.
