Weird wattage pull showing on a Cambium 2.4 1000

[alexivie]

Noticed this today on a WS-26-400-AC running Firmware Version 1.5.0.
(I had just power cycled the EPMP to see if the wattage would clear up, and reset the statistics before grabbing the screenshot below.)

A Cambium EPMP 1000 2.4 that should be pulling 4-8 watts is showing pulling 77+ watts.
The EPMP unit itself is working fine and not showing any problems... Any ideas?

Not weird, most likely a damaged current sensor. This type of damage is most often from ground current from a ground loop meaning you have 2 ground potentials, electrical service ground rods and tower ground rods and they are not bonded. And or your service ground rods are insufficient (add new ones).

I would RMA the unit for repair and then spend some time on your grounding.

Possibly add a couple NEW electrical service ground rods and if possible bond electrical service ground rods to tower ground rods.

Thanks for the info!
This is a 320' commercial radio and cell tower, but I will definitely take a look at grounding again when I get back up there.
I'll work on getting that unit RMAed soon!

Thanks!
