Connected to 3 phases, the S
172 and SYY 165 measure
sinusoidal voltages. The phase
sequence is arbitrary.
The relay operates as long as
all 3 phase-phase voltages
are within the set upper and
lower limits. The two limits
can be adjusted separately.
For S 172 applies that if one
or more of the phase-phase
voltages rises above the up-
per limit or drops below the
lower limit, the relay releases
after the set time period
whereas SYY 165 releases
immediately.
The relay operates again
when all 3 phase-phase volt-
age are within set limits. Hys-
teresis on operate is 2%.
Example 1
Mains monitoring
The relay measures if the 3
phase-phase
voltage
are
within the upper and lower
limits. The limits are adjusted
by the two built-in potentio-
meters.
Example 2
Monitoring load supply
The relay can protect loads,
such as heating elements,
against
overvoltage
thereby against increase in
current, which could other-
wise destroy the heating ele-
ments.
and
Undervoltage to ohmic loads
causes insufficient heating
capacity, and this can also be
monitored.
The relay cannot be used for
load monitoring if the load is a
motor, as the regenerated
phase voltage, at e.g. fuse
breakdown, is indefinable and
dependent on the mechani-
cal performance when the
failure occurs (see S 171).
