Overview
The power quality meter HC 6030 is an ideal device to power
monitoring in power quality when continuous monitoring to a
power system is required.
The HC 6030 provides metering for current, voltage, real and
reactive power, power energy, power factor, frequency energy
demand and 8 TOU channels with tariff to power energy. 24
programmable setpoints and 3 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 pulse counter to flow information or demand synchronized
trigger and etc.
The provided measurement to main of AC power and auxiliary
of 3 analog process inputs, 8 digital inputs, the HC 6030
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 two
digital communication ports RS485 and RS232 running the
ModBus(R) protocol. If analog values are required for direct
interface to a PLC, and of the monitored values can be output
to one of 4 isolated analog outputs and 2 pulse outputs. Process
variables can be measured using 3 analog inputs. Other
plant personnel can connect a front panel RS232 communication
port to a PC for simultaneous access of information.
The quality of the power system is important with increasing
use of electronic loads such as switching power or variable
frequency drives. With the HC 6030 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 HC 6030 assist in problem diagnosis.
More complex control is possible using the 8 switch inputs
which also can be used for status such as breaker open /
closed, or pulse counter to flow information or demand synchronized
trigger and etc.
