Abstract :
A new set of proposed American standards and recommended practices for transformers, regulators, and reactors has just been completed by the sectional committee on transformers of the American Standards Association. The new standards with their appendixes will combine in one volume considerable new material on standards, testing, and operating guides for transformers. It is believed that this will be the most complete single publication of its kind ever compiled. In order to obtain comments and criticisms from the entire industry, these standards are now being published for a 12-month trial period as “Proposed American Standards and Recommended Practices for Trial and Study.”
