What is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?
10 kV and below three-phase supply voltage allowable deviation of 10% for nominal system voltage.
220V single-phase supply voltage to allow the deviation of the standard system voltage +7%, - 10%.
Users who have special requirements for the allowable deviation of the supply voltage shall be determined by the agreement between the parties.
With other levels of power supply voltage fluctuations are as follows:
35kV and above supply voltage positive and negative deviation of the absolute value does not exceed the nominal system voltage l0%. Note: If the upper and lower deviation of the electrical voltage (both positive or negative), according to the larger deviation of the absolute value as a basis for measurement.
Industrial standard power 380V is a three-phase supply voltage, which allows the deviation of the nominal system voltage of 10% of the taxi, that is divided into: 342--418V.
