I have an Omni Pulse Monitoring V.4 that I got mostly to monitor a pulse output gas meter. The electrical service at our facility is 208v three phase.
If I install three current transformers at the service entrance (downstream of the main breaker, but upstream of the main breaker panel), as described in the three-phase 4-wire setup, will it monitor kWh accurately for all appliances connected to the breaker panel (single phase 120V and three-phase), or will it only monitor the kWh for three phase appliances accurately?
Monitoring 208 Three Phase
Re: Monitoring 208 Three Phase
Hello commandcenter, welcome to the forum!!
208 volts 3-phase generally implies that it is 120/208 volt 3-phase (3 hots and a neutral). For this kind of a system you would use 3 CTs like this: http://www.ekmmetering.com/information/ ... ml#answer8
Let me know if you have any questions.
Thanks,

The meter will measure all power flowing through it (so it will include all loads that are "downstream". In this case you would be metering everything that is fed by the main breaker panel. This would include all 3-phase loads and and single phase loads that come off of it. You could have a 3-phase air handler and a 120 volt coffee pot and the meter would measure both accurately.If I install three current transformers at the service entrance (downstream of the main breaker, but upstream of the main breaker panel)
