Abstract :
Calibration of instrument transformers with digital output requires determination of the time delay in the digital system. The time delay of reference systems must therefore be accurately known. Measurements on SP´s measurement system have shown the time delay to be 190/spl plusmn/21 ns. This result is very promising and adequate for the system.
