Processing Specifications

AC Voltage and
Current Inputs: 16 samples per power system cycle
Frequency Tracking
Range: 44–66 Hz
Digital Filtering: Cycle cosine after low-pass analog
filtering. Net filtering (analog plus
digital) rejects dc and all harmonics
greater than the fundamental.
Control Processing: Four times per power system cycle or 4
ms if no current or voltage card
(except for math variables and analog
signals used in logic, which are
processed every 100 ms)
