High-Voltage Testing and Calibration

All tests and measurements are made with instruments traceable to Australian National Standards, by staff highly experienced in testing measurement and calibration related to the electrical power industry. The particular capabilities that are within our NATA Scope of Accreditation are identified by NATA. Tests/calibrations outside the NATA Scope are identified with '(traceable)'.
