Heating tube power calculation formula

- Jun 17, 2019-

The heat pipe is a purely resistive load whose power = voltage × current


The relationship between active power and current and voltage in a single-phase AC circuit is: P=U×I


When the formula is used in a purely resistive circuit, it can be written as: W=V×A


  formula:


W——the unit of calculation of the active power P;


V——the unit of calculation of the voltage;


A - the unit of calculation of the current.


The current and power relationship of a three-phase four-wire 380/220 symmetrical pure resistive load is:


P=I÷1.44 / I=P×1.44
