Megger PAM420 Multifunction Phase Angle Meter
 
• Phase Angle Meter
• 2 channels: voltage, current and frequency meter 
• Timer
• Compact and lightweight
• Local calibration
• Rechargeable batteries
• Easy to use
The PAM420 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.
Application 
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
Features and benefits „ 
Direct digital reading to tenths of a degree (0.1°) – does not require calculation or interpretation. „ Designed for use in substation or industrial environments – transport case provided for rugged protection. „ Phase angle calculated from of any combination of two power signals to be measured giving broad application capability. „ Timer with high accuracy for contact or voltage trig. „ Local calibration.
Included
