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


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
