Method for detecting compressed air system leakage

A method of detecting leakage in a compressed air system having a compressor, the method comprising:

• configuring an electrical monitor to measure one or more electrical parameters indicative of operation of the compressor;
• identifying periods of time during which the compressed air system is not in use;
• analyzing running times and intervals of the compressor between compressor operations during one or more of identified periods of time to establish a baseline for constant air leakage, the baseline being derived from a regular pattern of brief air compressor operations;
• continuing to analyze running times and intervals of the compressor between compressor operations when the compressor is not in use;
• and
• notifying one or more users when running times and intervals between compressor operations vary from the baseline,
• wherein analyzing the running times and intervals of the compressor between compressor operations includes monitoring lengths of periods of running times and the lengths of intervals of non-operation of the compressor.
