Specifies general requirements and tests for all types of VTs and, in separate sections, specific requirements for single-phase VTs, for CVTs, for three-phase VTs and for Designation L VTs. Deals specifically with accuracy and short-term and long-term overvoltage ratings and applies the rated voltage factor to the VT as an entity, as well as to individual secondary windings. Primary windings are classified as ‘uniformly insulated’ or ‘non-uniformly insulated’. Categories of performance (A and B) are specified for three-phase VTs only. Includes many explanatory appendices and enlarges on the determination of primary and secondary currents and of temperature coefficients of error, and on the determination of errors under different conditions.
