Application Data

To obtain current measurement:
  1. Pass the wire carrying the current to be measured through the window of the CT transformer (acting as a primary winding).
  2. Connect the CT secondary to an ammeter with a 5 mA movement.
For high accuracy or higher VA burden rating:
  1. Choose a CT with a primary which is a multiple of the required primary rating and which has the accuracy or VA burden you require.
  2. Loop the wire carrying the current to be measured through the window a number of times equal to the multiple. This "winding" will reduce the ratio back to required primary rating.
