Answer / binod
To measure the current in the cicuit use ct.It is a current
tr(inst.tr).In L.V CIRCUIT WITH LOW CURRENT NEED NOT
REQUIRE A C.T(LOW CURRENT ,CAPACITY AM METERS WILL DISPLAY
THE CIRCUIT CURRENT).BUT IF CURRENT IS HIGH IN L.V CIRCUIT
THE C.T REQUIRMENT ARRIES DUE TO THE SIZE (BIG) OF AM
METERS & SAFETY FACTOR CONCERN.CT RATIO LIKE
100/1,150/1,200/1 LIKEWISE.IT MEANS EX;-(200/1) IF 200 AMP
FLOWS IN PRIMARY THAN THE SECONDARY AMP IS 1 AMP WHICH FLOW
TO THE AMMETER BUT THE METER WILL SHOW 200AMP IN ITS
CALIBRATED SCALE.
SIMILARLY FOR HT CURRENT MEASURMENT WE MUST USE A CT TO
MEASURE THE CIRCUIT CURRENT. DIRECT MEASUREMENT IS NOT
POSSIBLE DOE TO SIZE(BIG) & HUMAN SAFETY FACTOR CONCERN.
SO CONSIDERING THE RATIO THE AM METER WILL SO THE CURRENT
FLOWING IN THE CIRCUIT.ALL THE CTS CONNECTED IN SERIES IN
THE POWER CIRCUIT.AMP METERS ALSO CONNECTED IN SERIES.
