How to identify impedance of LPVT is sufficient to ION9000 voltage input impedance ?

Details: 

- LPVT impedance = 10MOhm

- ION9000 impedance = 5MOhm

Hello @Aduldech ,

ION9000 meters do not support Low Power VTs. ION ION9000 meters do support LVCTs.

Hello @Charles_Murison 

In case I connect LPVT to LPVT hub. Then, converting to voltage 110V/sqrt(3) by LPVT transducer.

The LPVT transducer able to supply voltage to ION9000?

In addition, Is it sufficient that we consider burden that LPVT transducer supply to ION9000. How does the impedance affects to LPVT transducer and our meter?

Best regards,

Hello @Aduldech ,

I have never used LPVT transducers before so I cannot speak to how effective they could be with ION9000 meters. Meter's voltage inputs are expecting a sinusoidal voltage input, 57 - 400 V L-N / 100 - 690 V L-L (RMS).
