Schneider LPVT

[Vegemite]

Schneider make new Low Power VTs for use in their MV Switchgear. They can work up to 20 kV and have an output of 3.25/root 3 volts.
Does anyone have information on how to integrate them with a SEL751 relay with LEA RJ-45 inputs?
What kind of cable is needed and what length & method of installation constraints are there?

I was looking at these last month, and I can tell you that Schneider is not the only one with LVPT. ABB has its own KEVA C, which has a lot of cabling options, SIEMENS is using their own version. I couldn't get these LVPT from either Schneider or SIEMENS as they won't sell them as separate equipment so we ended up buying with another manufacturer. We ended up buying from Zelisko at a much better price.

In any case, the output cable is a 3 to 5 meters 3-pole M8 cable, meaning is an analog signal. There are connectors you can buy from M8 to digital output, and from there to anything you need. The sensors are designed for specific MV separable connectors sizes, so be careful when selecting the proper model. These came too in different accuracy, so be sure to buy 0.2.
