Pumping Station Motor Analysis
This test was performed at a pumping station that was using multiple 600HP motors and a VFD drive. The reported problem was the plant was not receiving adequate power output from the motors during peak times. It was not possible to connect to the inputs of the motors themselves so an MPQ2000 was connected to the output of the VFD and the following measurements were recorded.

Rapid Voltage Change (RVC)
A rapid voltage change is a fast rise or fall of the RMS voltage. This can be caused by the switching on of a specific load or by a sudden change in source voltage. Sudden source voltage changes can occur in solar grids when the sun is obscured by clouds. Source voltage changes can also occur in wind farms when then wind speed decreases. Load switching can cause a rapid voltage change if the rating of the load is a significant fraction of the fault level of the supply voltage.

EN50160 Report
The EN50160 test is a European standard that specifies the main characteristics of the voltage at a network user's supply terminal. The standard applies to public low voltage, medium voltage and high voltage AC electricity networks under normal operating conditions. In the UK, the test is known as a BS50160 test.
