New Online Seminar for Overcurrent Testing is Now in Production

We should have started this several months ago, but we’re on task now and the amount of content has already doubled since we first envisioned what this seminar would look like. It looks like we’ll cover over 40 hours of content for this online seminar about overcurrent testing. If the How to Test Protective Relays Online Seminar is any indication, it will probably be closer to 60 hours.

Here’s an index of the topics we plan to cover:
