The comparison will be based on measurement of ratio error and phase displacement of a transfer instrument current transformer in the range (4 - 10) kA/5 A. The measurements will be performed at the range (1 - 120) % of rated primary current at a given burden. The pilot laboratory will be the Czech Metrology Institute in Prague, the Czech Republic.
