Circuit for Checking and Calibrating the CVR-1 Relay Removed from Case
of voltage. For example, any one of the fol
lowing conditions contributes
to
a shorter
time delay.
1.
A lower damping factor.
2. A greater voltage deviation from the
center of the set bandwidth.
3. A lower bandwidth.
Should the conditions be reversed, a
longer time delay is indicated. It is difficult
to make a general statement about time de
lay except that itis not fixed. It can be said,
however, that for step deviations from the
band center equal to 75% of total set band
width, time delay may be varied from
11
to
60 seconds by adjustment of the damping
magnet and keeper. Correction for greater
