I recently attended a training session with Omicron in Germany, looking at their primary injection test set for earth electrode and line impedance testing. We looked at how to set up a current injection, potentially up to 100 A, down an Overhead line or Feeder cable to achieve good separation between the electrode under test and the auxiliary electrode.

Previously, test methods have relied on dedicated cables for the measurement, which has limited the available area to deploy the auxiliary electrode, owing to land usage constraints and roads. So, being able to use something in a built-up environment on electrically large HV systems avoiding road closures, etc. comes as a breath of fresh air to a lot of engineers facing this problem.

Firstly I’d like to take this opportunity to wish our Clients, friends, students and Blog subscribers SEASONAL GREETINGS and a very prosperous New Year.

I’m actually in Gibraltar writing this post completing a personal goal of mine. That’s topping up my sailing qualifications in preparation for my exciting challenge later next year to the Southern Ocean competing in the Clipper Round the World Race (more on that next year).
