Description

Active power is calculated as: P = U  I  cos, cos represents the power factor, purely resistive loads (such as incandescent, heater, etc.) the power factor is generally close to 1, inductive and capacitive load load power factor 0-1; therefore purely resistive load test time, P is substantially equal to or close to U  I; test inductive or capacitive loads (such as refrigerators, washing machines, televisions, computers, etc.) when, P Less than U  I As for the specific number to keep the power factor related to power factor different for each appliance, please show table prevail.
