This paper presents modern techniques to study step voltage regulator (SVR) -distributed generation (DG) interactions in distribution systems using electromagnetic transient programs. Digital models represent physical characteristics of both SVR and DG and the associated control systems. These modeling techniques may effectively simulate realistic aspects of SVR and DG real time operations.

This paper describes current technology and application for Rogowski Coils, which serve in the role of current transformers for measuring power system currents for protective relaying or other measurement purposes. Rogowski coils have low-energy outputs. They offer a number of application advantages including compact size, light weight, and linearity (do not saturate like conventional iron-core current transformers). A forthcoming Guide PC37.235 from the IEEE PSRC will give detailed information and help for users.Index Terms -Rogowski Coil, Current Transformer, Protective Relaying.
