Voltage Deviation Event detection trigger. 1/2-cycle rms voltage ≤ 87% or ≥115% of set nominal 
Adaptive waveform deviation detection of transient events.
Voltage Deviation Event Storage 8 cycles waveform data (-1...+3 cycles at event start and -3...+1 cycles at the
event end) Continuous rms voltage trend, up to 2 minutes.
Periodic (PRMS) Data Logging Minimum, Maximum and Average rms voltage recorded for each 10-minute
