Description
The Model 292 Frequency Monitor is designed to monitor power
line frequency. It is intended for systems where line frequency
variations will cause improper operation of electrical equipment.
A solid-state sensing circuit
drives an internal electromechanical relay which is energized
when the line frequency is correct. Operating power is drawn
from the same line being monitored.
The Model 292 Frequency
Monitor is set to the over and/or under frequency trip points
using ten binary-coded switches. A frequency variation outside
the trip points causes the internal relay to drop out and
an appropriate LED indicator to illuminate.
Applications for the Model
292 Frequency Monitor include stand-by power plants, portable
power supplies, and windmill generators.
