Introduction
The power quality meter as Enhanced IED VP-2040 is an ideal
device to power monitoring in power quality when continuous
monitoring to a power system is required.
The VP-2040 provides metering for current, voltage, real and reactive
power, power energy, power factor, frequency energy demand.
Programmable set-points and optional assignable output relays allow
control functions to be added for specific applications. This includes
basic alarm on over/under current or voltage, unbalance, demand
based load shedding, and capacitor power factor correction control.
More complex control is possible using the 8 switch inputs which also
can be used for status such as breaker open/closed, or optional
pulse counter to flow information or demand synchronized trigger and
etc.
The provided measurement to main of AC power and digital inputs
and digital outputs, the VP-2040 may be used as a data gathering
device for a plant automation system that integrates process,
instrument and electrical requirements. All monitored values are
available via digital communication ports RS485 running the
ModBus® protocol. If analog values are required for direct interface
to a PLC, and of the monitored values can be output to one analog
output and 2 pulse outputs.
The quality of the power system is important with increasing use of
electronic loads such as switching power or variable frequency
drives.
With the VP-2040 auxiliary input/output, any phase
current/voltage can be displayed and the harmonic content
calculated. By knowing the harmonic distribution, action can be taken
to prevent overheated transformer, motors, capacitors, neutral wires
and nuisance breaker trips. Redistribution of system loading can also
be determined. Waveform and chart recorder printouts available from
the VP-2040 assist in problem diagnosis.
