Please Explain the Principle of Weak InFeed Echo Permissive Over Reach Transfer Trip Schemes?
Rahim submitted this question to the Ask Chris section of the RelayTraining.com website. Most line distance protection schemes assume that the system will always be able to supply enough amps to make the relays trip. However, there are many scenarios on transmission systems across the world where you could have

When I test induction disc relay type … Is the pickup value the value at which the disc starts rotating?
This question was submitted via the Ask Chris form where you can ask me relay testing questions that I can hopefully answer. Creating test plans for digital relays is often difficult because you can have ten relays with identical model numbers that have completely different functionality. Conversely, ten induction disc relays of
