This chapter describes the options available to users with applications that require 

advanced setups. Although the Energy Platform is designed to capture data no matter 

what the setup is, users are able to configure combinations of setups unique to their task 

applications.

Setup: A fixed condition of parameter thresholds based on IEEE 1159 rms voltage 

variation, that determines what will constitute an event. In addition, other parameters 

such as demand or harmonic distortion, have preset thresholds that the user can modify.

Event: The Energy Platform can record three types of events namely sag, swell or 

aggregate snapshot. A sag or swell event is detected when the rms threshold limits are 

exceeded by +/- 10% of the nominal input. Aggregate snapshot is a timed snapshot for 

which a trend plot can be viewed over a user selected time interval. For each type of 

event, the min and max values and time stamp are displayed for analysis.

Parameter threshold: A value that the 

Energy Platform

 compares to a measurement to 

decide if an event occurs. Also called a limit. For example, if the input voltage is 

measured as 135 Vrms, and the parameter threshold for voltage is 132 Vrms, Energy 

Platform saves this limit crossing to memory as an event.
