The Complexities Of Differential Protection

Differential protection is based on the fact that any fault within a piece of electrical equipment will cause the current that enters it to be different from the current that leaves it. What seems like a simple subtraction of outgoing current from ingoing current is, in reality, much more complicated as the power system is anything from an ideal system. Capacitive charging currents, non-transposed lines or asymmetrical communication causing phase rotation, drifting time synchronisation, tapped lines and transformers are just some examples of features that leak or transform current flowing on the line or influence the data sent between intelligent electronic devices. It requires advanced stabilisation methods to create a reliable line differential protection scheme. Differential protection is easier to integrate into a protection philosophy as distance protection, as it is a unit protection. It delivers greater consistency of performance at the cost of greater reliance on hardware. Some form of high bandwidth, low latency communication is required in between the line ends in order to exchange analogue information for the line differential algorithm to process. Typically, this is a direct fibre optic cable.
