Connection problems are a common issue encountered during electric motor testing. This is particularly noticeable when you first implement a motor circuit testing program. Simply put, resistance is the opposition to current flow. In a motor and motor circuit there are several things that will affect the measured resistance. Read this month's tip to find out what you need to be aware of when measuring poly-phase circuits and the properties that will affect balanced resistance.
