Asymmetry definition.

Asymmetry is an indicator of
the mains quality and it is
defined as the absolute val-
ue of the maximum devia-
tion among the mains volt-
ages, divided by the nominal
voltage of the 3-phase sys-
tem. The definition changes
according to the voltage ref-
erence:

Tolerance definition.

Tolerance is another indicator
of the mains quality and it is
definied as the absolute val-
ue of the maximum deviation
of the mains voltages from
the nominal voltage, divided

Mode of Operation (cont.)

Connected to the 3 phases
(and neutral) DPC01 and
PPC01 operate when all 3
phases are present at the
same time and the phase
sequence is correct. It can be
decided whether to monitor
upper and lower voltage level
of each phase or their asym-
metry and tolerance.

Voltage level monitoring:
if one or more phase-phase
or phase-neutral voltage
exceed the upper set level or
drop below the lower set lev-
el, the red LED starts flash-
ing 2 Hz and the respective

output relay releases after
the set time period.

Asymmetry and tolerance
monitoring:
if one or more phase-phase
or phase-neutral voltage
exceed the set levels the red
LED starts flashing 2 Hz and
the respective output relay
releases after the set time
period.
Note: For both functions, if
the phase sequence is
wrong or one phase is lost,
both output relays release
immediately. Only 200 ms

delay occurs. The failure is
indicated by the red LED
flashing 5 Hz during the
alarm condition.

Example 1
(Mains monitoring - over and
under phase-phase voltage)
The relay monitors over and
under voltage, phase loss
and correct phase sequence.

Example 2
(Motor monitoring - starting
and operating load -asym-
metry and tolerance of
phase-neutral voltage)

DPC01 and PPC01 ensure
correct starting and operat-
ing conditions. They monitor
the voltage level, phase
sequence (correct direction
of the motor rotation) and
asymmetry.

Frequent failures are fuse
blowing and incorrect volt-
age level. In case of fuse
blowing the motor regener-
ates a voltage in the inter-
rupted phase. The relay
detects the failure and reacts
due to excessive imbalance
among the phases.
