EKM-Omnimeter-I-v3-Install Question
Posted: Tue Nov 28, 2023 8:28 pm
Hi,
Now we are using the EKM-Omnimeter-I-v3 for development and we have some questions about installation.
By the EKM-Omnimeter-I-v3 spec if the utility power system uses the "120/240V 120/208V Single-Phase 3-Wire / 2 Lines & Neutral" the spec suggests adding the L1 & L2 CT sensor.
Is it necessary to add two CT sensors? If we only install the L1 CT sensor. Does it have some risks in using the meter? Or just can't get the L2 current value only?
Because in our knowledge the AC L1 L2 current rms value shouldn't be different so we can calculate the total watts using the L1 to L2 voltage and the L1 current to calculate?
Thanks
