Searching for reference about insulation coordination, I consult thread238-232606 from 2008 and though I should comment about what I find.
Background
First, I was questioning myself if a ACWU90 600V cable was suitable for a 600V application (Québec, Canada) considering that, by common practice...
Hi
I have a number of feedthrough connectors TCF125-128AL for mono DLO 535 cable. The diameter of one end is too small. It's cause of varying OD diameter of the cable manufacturers. Southwire would have fit but not Carol.
My men proposed to grind the opening end for 3/32 inch width.
I was...
Hello
I'm looking for reference and opinion about Fault current limiter.
Question Is there any papers or reference that allow to calculate, to compute, to quantify peak short-circuit reduced by a current limiter on all the load side assemblies?
Context :
Arc-Flash, short-circuit and...
I'm actually designing a grounding systems for arctic climate.
This thread is a follow up of an older thread thread238-196015 as to be a sample application.

I would like to find documentation about how the current direction could affect the proper fonctionning of a protective relay.
We are connecting a 600V power house (PW1) to a 4160V power house (PW2) throught a step-up transformer.
The grid configuration can allow to feed PW2 with PW1 and vice...
Hi
Question : Does a volatage regulator for 69kV line can could be used for a 120kV and vice versa? Does a auto-regulator on a line supplying 10MW would be affected and/or need to be change if we rise to 20MW.
Link about high-voltage regulators would be appreciated.
