Megger PAM 420 – Multifunction Phase Angle Meter

• Measures phase angle, voltage, current, and frequency in power systems
• High-accuracy phase angle measurement for protection and commissioning work
• Supports single and three-phase testing across a wide input range
• Vector diagram display for clear visualisation of phase relationships
• Data storage and PC interface for result analysis and reporting
• Portable, rugged design for substation and field environments

The Megger PAM 420 Multifunction Phase Angle Meter delivers greater insight into power system behaviour. It measures phase angle, voltage, current, and frequency, which helps technicians verify system performance during commissioning and maintenance. In addition, the vector diagram display provides a clear visual view of phase relationships, making complex measurements easier to understand. The instrument supports both single and three-phase systems, which adds flexibility in the field. It also stores measurement data and allows transfer to a PC for further analysis. A clear display keeps results easy to read, while the rugged, portable design ensures reliable operation in demanding environments. Overall, the PAM 420 helps engineers carry out detailed and confident phase analysis.
