Berkeman: -CCVT = Capacitive Coupling Voltage Transformer (used in Electrical Substations to step down huge potentials for metering purposes for protective relays) -TF= Short for Transformer Dlgoff: So here is the scenario. We have a huge substation with very long runs between outdoor...

I have not found a straightforward explanation on how to perform voltage drop calculations for cables used for instrumentations purposes. Suppose you have Current Transformer (CT) and Potential Transformer (PT) connections coming into a relay (IE SEL421). If we have a cable that runs from the...
