CP1554 ‘Future proofing the measurement transformer standards’
Formal title: Future proofing changes to the measurement transformer standards in CoPs 1, 2, 3, 4, 5 and 10
CP1554 looks to future proof the measurement transformer standards in Code of Practices 1, 2, 3, 4, 5 and 10
Metering Codes of Practice (CoPs) rely on the British Standard Institution (BSI) / International Electrotechical Commission (IEC) standards for measurement transformers (i.e. current transformers and voltage transformers).
These standards are reviewed every five years and as a result, could be extended without amendments, amended by an industry expert group, or withdrawn. When they are amended, their reference number may change, creating issues for the relevant Balancing and Settlement Code (BSC) Party or Party Agents.
These issues could lead to the stranding of measurement transformer stocks, which is costly to the BSC Parties and Party Agents.
