changes that will be required. The FDIS document will go to IEC and will be circulated. The document and comments will be submitted to IEEE and REVCOM for approval. Old Business C57.156 Patrick McShane noted that promised changes were not made and an annex on fire – prevention was removed. There were also wording changes on fire prevention. New Business Phil Hopkinson Distribution transformers can be made up to 10 MVA and can step up or down – between primary and secondary voltages. Do we need a Class 1 power transformer classification? Renewable application transformers are Power, Class 1 transformers. A motion was made to form a joint TF to clearly define the bounds between Power and Distribution transformers, which would include Power Transformers SC, Distribution Transformers SC and Standards SC. It was further noted that C57.12.80 would need to be updated where definitions would be affected. Adjournment The meeting adjourned as scheduled.
