The PAM420 multifunction phase angle meter is specifically designed for measurements on electrical power systems. It is capable of displaying phase angle, voltage, current, frequency, and timing. The phase angle is calculated from the relationship between two power signals, which can be two currents, two voltages or any combination. Currents up to 25 A and voltages up to 500 V can be applied directly to the instrument and the current input range can be extended by using external current transformers.
The PAM420 is suited for checking polyphase metering installations, testing protective relays, make comparative test in electrical substations, and verifying the phase angle deviation on power transformers. It is able to give you a direct digital reading to tenths of a degree (0.1°) and doesn't require calculation or interpretation. It can be calibrated locally, has a timer with high accuracy for contact or voltage trig, and comes with a rugged transport case for protection.
