Sample Size Determination
Control Charts. This procedure is designed to help determine the appropriate sample size and parameters for common control charts. The design is based on: 1. the magnitude of a shift away from the centerline that you wish to detect. 2. the average acceptable run length if such a shift occurs before an out-of-control signal is generated.

Generator Sizing: A Step By Step Guide
Power factor is very important for matching the size of your load to a generator: a generator that is rated at 100kVA and has a 0.8pf will be too small to power equipment that requires 100kW of actual power. *Generators have a power factor of 0.8. So, if the the
