factor (true and displacement), power
(P, Q, S) and frequency
Time stamping to 1 second
Four trend curves: 1 minute, 1 hour,
1 day and 1 month
■ every second for one minute for the
1-minute curve
■ every minute for one hour for the
1-hour curve
■ every hour for one day for the
1-day curve
■ every day for one month for the
1-month curve
Forecasting of the values for the trended
parameters for the next four hours and
next four days
Triggered manually or by alarm, 3-cycle,
128 samples/cycle on 6 user configurable
channels
■ adjustable pickup and dropout
setpoints and time delays, numerous
activation levels possible for a given
type of alarm
