Megger PAM420 Multifunction Phase Angle Meter

Megger PAM420 Phase Angle Meter

The PAM420 is specifically designed for measurements of 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.

 Key Features of the PAM420:

• Versatile Measurements: The PAM420 can display phase angle, voltage, current, frequency, and timing, making it a comprehensive tool for various electrical measurements. The phase angle, a critical parameter in power systems, is calculated from the relationship between two power signals, which could be two currents, two voltages, or any combination thereof.
• Direct High-Range Inputs: The device can handle currents up to 25 A and voltages up to 500 V directly applied to the instrument. This capability facilitates direct connections without the need for intermediate devices, streamlining the testing process.
• Extended Current Input Range: For applications requiring measurements beyond the direct input capabilities, the PAM420’s range can be extended using external current transformers. This feature allows for flexibility and adaptability in various testing environments.
• Precision and Ease of Use: It offers direct digital readings to tenths of a degree (0.1°), ensuring high precision without the need for manual calculations or interpretations, which can save time and reduce errors during testing.
• Local Calibration and High-Accuracy Timer: The instrument can be calibrated locally to ensure ongoing accuracy and reliability. It also features a high-accuracy timer for contact or voltage triggers, enhancing its utility in time-sensitive applications.
• Rugged Transport Case: The PAM420 comes with a rugged transport case, which provides robust protection for the instrument, making it suitable for use in harsh or challenging field conditions.

Applications of the PAM420:

• Polyphase Metering Installations: Ideal for checking and calibrating metering setups, ensuring they are accurate and meet required specifications.
• Protective Relay Testing: Essential for testing protective relays to verify their operation and timing per system requirements.
• Comparative Tests in Electrical Substations: This can be used for conducting comparative tests to assess the consistency and reliability of different parts of the electrical system within substations.
• Verifying Phase Angle Deviation on Power Transformers: This helps in verifying the phase angle deviation in power transformers, which is crucial for the transformer’s performance and longevity.
