Osborne’s Potential Transformers

Osborne Potential Transformers (PT’s) are used to reduce higher system voltages to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when potential transformers are to be used for power measuring applications.
