Megger PAM410 Phase Angle Meter
Make phase angle checks simpler with the Megger PAM410 Phase Angle Meter. Designed for electrical power systems, it shows the phase relationship between two signals as a direct digital reading.
Compare two currents, two voltages, or a current and a voltage. Switchable inputs let you choose the combination needed for your test, with direct connections for currents up to 25A and voltages up to 500V.
Use the PAM410 for metering checks, protective relay testing and transformer phase angle checks. Its rechargeable battery and compact design make it practical to carry between test locations.

Why choose the Megger PAM410?
✓ See the phase relationship directly
The PAM410 displays the angle between your two selected signals. You can read the result directly, without working through a separate calculation.
Its measurement range covers 0–359.9°, with results displayed to one decimal place.
✓ Cover several power system checks
Use the same instrument when checking multiphase metering installations, testing protective relays or comparing measurements in substations.
The PAM410 also helps verify phase angle deviation on power transformers. Its choice of current and voltage inputs supports these different applications.
✓ Take the instrument where you need it
The compact body measures 260 × 140 × 55mm, excluding the handle. A transport case is included to protect the instrument between jobs.
The complete set weighs 3.5kg with its accessories and case. Rechargeable battery power and the supplied mains charger support regular use in substations and industrial environments.

❓ Frequently Asked Questions (FAQ)
Q1: What does the Megger PAM410 measure?
A. It measures the phase angle between two electrical power signals. You can compare two currents, two voltages, or one of each.
Q2: Is 0.1° the measurement accuracy?
A. It is the display resolution. Accuracy depends on the input level, with ±0.5° specified above 10% of the voltage or current range.
Q3: Can I measure currents above 25A?
A. Currents up to 25A can be connected directly. External current transformers can extend the current input range.
Q4: Is the PAM410 battery powered?
A. Yes. It has an internal rechargeable lithium-ion battery, and a mains adapter for charging is included.
Q5: Are test leads included?
A. Yes. The supplied GA-00082 set contains four 2m test leads with stackable safety plugs.
Q6: Can I replace the internal battery myself?
A. Megger specifies that the rechargeable lithium-ion battery must only be replaced by an accredited service centre.
