ammeter isnot connected as a shunt across the terminals of a low-resistancelink inserted in the main circuit whose current is to be measured,exactly as in the case of switchboard ammeters for direct currents.There are two reasons why this arrangement would not be permissible: (a) An alternating… … ammeter cannot be multipliedby a constant factor to give thetotal current in the main circuit,(b) It is objectionable tohave the ammeter in electricalconnection with, high-voltagemains. The use of the seriestransformer is, therefore, prefer-able on the grounds of bothaccuracy and safety.…
