Abstract :
An experiment was conducted to study the feasibility of a remote (noncontact) ammeter based on phosphor thermometry. Elevated surface temperature (due to current) of a small transformer was measured by employing phosphor thermometry. A nearly linear relationship between surface temperature and current indicates potential use for this technique. Some modifications to the technique with the aim of reducing relatively long thermal stabilization time, observed in this experiment, are suggested.
