Goals and Symptoms
The ION meters with Sag/Swell and Transient detection require the user to configure the Nominal Voltage correctly. The meter is shipped with this value at 0 so the Sag/Swell detection sub-system is disabled. But if the user enters an incorrect value for the Nominal Voltage (for example 100 when it should be 120, or 277 when it should be 347) then the sub-system will become active but then begin to CONTINUOUSLY generate erroneous events, logs and waveforms. Hence, the Log Server will never be able to keep up.
Causes and Fixes
ResolutionSet the Nominal Voltage to the correct value. Perhaps look at a waveform to see what it should be. Or check the outputs of the Power Meter module.
