- Specification for Calibration and Performance Testing of Secondary Current Sensing Coils and Weld Current Monitors used in Singl
This specification sets forth accepted methods for testing and describing the performance of Rogowski-type air core current sensing coils (CSC) and weld current monitors (WCM) used in the measurement of single-phase ac resistance welding currents. A definition of terms relevant to this measurement is included. CSC and system tests and calibration methods are described in detail. Detailed information that shall be made available to the user are prescribed.
