3.2 Mains
Basic information and measuring of the mains, deions state.
3.2.1 2/1 MAINS
Summary information about mains voltage,
generator voltage, active and reactive power on
mains as well on generator
MCB: mains deion control (switch state
indicate real state)
GCB: generator deion control (switch
state indicate real state)
3.2.2 2/2 MAINS (Measure)
Information about voltage, current, active and
reactive power in all phases of network, the total
active and reactive power, frequency. The bargraph shows the nominal voltage grid voltage
warning and emergency limits and under-voltage
(surges).
3.2.3 2/3 MAINS (Protections)
Mains protections. Flashing lights indicate
exceeded warning limits, a continuously lights
indicate exceeded emergency thresholds.
V : undervoltage (without delay)
V : overvoltage (without delay)
V : voltage unbalance (without delay)
L1-L3: indicate phase in which is out of limits
Hz : underfrequency (without delay)
Hz : overfrequency (without delay)
ExErrMns: External information about mains error (external input)
VJmp: indicator of vertor jump, numeric value under indicator shows the
actual value of vector jump (value is indicated 5s after maximum of vector
jump is detected)
GenErA: overall mains voltage error (the sum of partial voltage failures with
delay)
GenErHz: overall mains frequency error (the sum of partial voltage failures
with delay)
PhaseSeq: indicator of wrong phases sequence on mains
