active power vs true power?
I am looking for a meter to measure true power. Many meters claim to measure active power, is this the same value?
Yes, it is. All circuits contain some degree of inductance and capacitance in addition to resistance. In a normal circuit, on alternate half cycles, the inductance and capacitance take and return power to the source. They are called reactive loads. (Of course, if you are charging a capacitor bank, they only take power until you are ready to use it.) Resistance only takes power and can usually be thought of as the actual work being done. That power is called various names but the consistent denominator in them is a reference to actuality or activeness. It is measured in watts while reactive power is measured in volt-amps (and, as that implies, includes the "true" power as well as the moving back and forth power). However, reactive power (and current) is physically real even if not thought of that way and circuits have to be designed to carry it back and forth, not just with the "true" power in mind.
