MOTOR CURRENT SIGNATURE ANALYSIS. A POTENTIAL DIAGNOSTIC FOR AIR CONDITIONERS.

Author(s) : MILLER W. A.

Summary

RECENT ADVANCEMENTS IN MODERN ELECTRONICS HAVE MADE IT POSSIBLE TO COLLECT THE VARIOUS < TRANSIENT NOISE > SIGNALS THAT ARE PRESENT ON ELECTRIC POWER LINES OF MOTOR-DRIVEN EQUIPMENT WHILE USING A SIMPLE NON-INTRUSIVE, CLAMP-ON INDUCTIVE PICKUP. ELECTRONIC FILTERS ARE USED TO ANALYZE THE NOISE SIGNAL WITH AN ON-THE-SPOT, REAL-TIME ANALYSIS. AN EXPLORATORY STUDY EXAMINED THE POTENTIAL FOR USING THE MOTOR CURRENT SIGNATURE ON HEAT PUMPS AND AIR CONDITIONERS AS A DIAGNOSTIC TOOL. PRELIMINARY RESULTS SHOW THAT THERE IS SOME CORRELATION BETWEEN THE MOTOR CURRENT SIGNATURE AND THE PERFORMANCE OF A HEAT PUMP. HOWEVER, TESTS AND ASSOCIATED ANALYSIS WERE LIMITED.
