Overview
The Yokogawa 103-402-FCAD is an analog switchboard power factor meter designed for three-phase AC electrical systems. Power factor meters measure the power factor of an AC electrical system defined as the ratio of the real power flowing to the load, to the apparent power in the circuit. This meter features water-tight construction, shock-resistant pivot and jewel movement, and IP54 splash-proof design, making it suitable for harsh industrial environments.
