Updated requirements for insulation and performance in fault conditions.

Historically, current transformers were governed by IEC 60044-1, and voltage transformers by IEC 60044-2. The IEC consolidated and modernized these older standards into the unified IEC 61869 family. Part 1 serves as the foundational document, while subsequent parts (like Part 2 for CTs and Part 3 for VTs) build upon these basics with specific technical requirements.
