The primary circuit is largely unaffected by the insertion of the CT . Accurate current transformers need close coupling between the primary and secondary to ensure that the secondary current is proportional to the primary current over a wide current range.

If the burden resistance is much less than inductive impedance of the secondary winding at the measurement frequency then the current in the secondary tracks the primary current and the transformer provides a current output that is proportional to the measured current.

In its primary current sense, the reporter Heda Bayron wrote disapprovingly in a recent Business World magazine, " In the Red Sea resort of Sharm El Sheikh in the Sinai Peninsula, topless European women cavort in front of a group of Arab men ."

Its primary current activity is, according to the company, the " development of the unconventional gas reservoir located on the Arkansas side of the Arkoma Basin " and in its press statement, its " operations are focused within the United States on development of two natural gas reservoirs located in Arkansas and Pennsylvania.

Mining ore trucks and fuel tankers are the primary current ( 2013 ) commercial users of the highway, which also remains a popular tourist route ( cars, RVs, buses ), and provides a means for the WP & YR to offer economically-priced train excursions connecting at Fraser to buses based at Skagway for the cruise ship industry, or to / from Carcross and Whitehorse to the north.
