Megger PAM410 Phase Angle Meter

The Megger PAM410 Phase Angle Meter is a sophisticated instrument that measures the phase angle between two power signals whether they are two currents, two voltages or a combination of both. The high-resolution measurement gives degree readings to 0.1˚ and the meter has a maximum voltage input of 500V and a maximum current input of 25A. This makes it suitable for checking metering installations, testing prospective relays, making comparative tests in electrical substations and checking phase angle deviation on power transformers.

The Megger PAM410’s LCD screen displays readings directly in degrees without the need for additional calculation or interpretation. The rugged case is ideal for use in challenging substation or industrial environments whilst the comparatively low weight (1.2kg) makes it easy to transport. The meter has fully rechargeable batteries and is supplied with a charger, test leads and a transport case.
