1. APPLICATION
The
PCE-
ND10 meter is a digital programmable panel
meter destined for the measurement of the 3-phase, 4-wire
power network parameters in balanced and
unbalanced systems. It is also capable of displaying
measured quantities and their simultaneous digital
transmission. The meter is also capable of controlling and
optimization of the power electronic devices, systems, and
industrial installations. The meter can be used for measuring:
RMS value of voltage and current; active, reactive and
apparent power; active and reactive energy, power
parameters; frequency, 15-, 30- and 60-minute mean active
power and THD. Additionally, a current in the neutral wire
is calculated from the phase current vectors . Voltage and
cur-rent values are multiplied by given voltage and current
ratios of measuring transformers. Power and energy
indications take into account all programmed ratio values. Any
and all measured values can be sent to the master via the
RS-485 interface. The relay outputs signal alarm when
selected parameters exceed set limits. Impulse output can
be used for consump-tion check of the 3-phase real energy.
This meter is also able to detect and signal incorrect phase
sequence. The meter is powered by the measuring
circuit, i.e. from the voltage output.
There is a galvanic separation between following units of
the meter:
- voltage and current inputs,
- RS-485 output,
- pulse output.
