If you count up the number of protective devices in a typical manufacturing facility, it will surprise you to learn that you have lots and lots of them. Now what is scary is that for roughly 33% of these protective devices, you probably were not aware they even existed in the factory. Even scarier is the fact that only approximately 30-40% of all protective devices that we know about are maintained. That said, upwards of 20% are already in the failed state.

1) Understand protective devices and multiple failure analysis
2) What constitutes a “hidden failure”
3) How to develop a maintenance strategy to ad dress them
