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.
