In a GIS, can I connect an electronic current transformer to any kind of IED or are there incompatibilities between different systems or manufacturers?

ABB's answer

Today, most electronic current transformers used in high-voltage equipment come with either a low-voltage analogue interface or with a digital fibre optic interface as according to IEC61850-9-2LE. LE stands for "Light Edition" and refers to an implementation guideline issued by the UCA international user's group. The implementation defines a sensible subset of the vast range of IEC61850-9-2 options to ease implementation in electronic current and voltage transformers.
