摘要：
Relays rely on the current transformer to produce a secondary current that faithfully reflects the primary current for proper operation. In some instances this isn't the case. This paper will look at cases where severe ct saturation can be a problem, review the real time digital simulator inputs to the relay, and look at what mechanisms in modern line current differential relays are used to mitigate the problem.
