the iq dp 4000 is a microprocessor based monitoring and protective device that provides complete electrical metering and system voltage protective alarming. in one compact, standard package the iq dp 4000 will provide an alternative to individually mounted and wired conventional meters and switches.
key features include:
- monitors the following parameters phase currents, phase l-l and l-n voltages, power and energy including real, reactive, and apparent, demand power and current, and % total harmonic distortion. the meter also provides a protective alarming function as well as provides minimum and maximum values of metered parameters.
- enhanced features the iq dp-4000 provides all the capabilities of the iq data plus ii and more. the new meter offers improved accuracy, % thd, va, var-hours, va-hours, demand values and min/max values.
- reduced component cost less equipment and installation cost with increased functionality and improved accuracy over discrete analog meters.
- communications capability the ability to communicate to a central monitoring point eliminates manual clip-board style data-logging.
- accuracy maintaned from 3 to 300% of nominal current range the iq dp-4000 offers 0.3% full scale accuracy of voltages and currents and 0.6% of full scale accuracy of power and energy parameters.
- demand and energy monitoring the iq dp 4000 provides power, energy, and power demand data for accurate load profileing that can be used to determine where energy management opportunities may exist as well as to establish a base line for monitoring an energy management system success.
- complete metering in a communicating compact package trending capabilities via communications offer you the ability to monitor equipment loads, power factor, k-factor, kva, kvar to avoid equipment damage from utilizing undersized equipment, and maximize equipment life, efficiency, and reliability.
- protective alarming alarming is available via communications, led at device, or optional relay output contacts are available for over and under voltage, current and voltage phase loss, and voltage unbalance to alarm on potentially costly voltage and current conditions.
- minimum and peak values of most metered parameters this data offers the ability to accurately trend peaks and minimums especially if trending is accomplished via communications at pre-programmed fixed intervals.
- troubleshooting data two alarm buffers store the alarm type and all metered values at the time of alarm to aid in troubleshooting efforts. this data is stored in a non-volatile memory.
- % total harmonic distortion of all phase voltage and currents continuous power quality monitoring can detect the presence of harmonic problems that may be the cause of costly power and production outages and equipment malfunction and/or damage.
- application at any point in the electrical distribution system the iq dp-4000 offers 512 different pt ratios and 512 ct ratios and can be applied from 120v to 510kv and 5a to 12,800a.
protection features:
overvoltage range 105% to 140% (5% increments)
undervoltage range 60% to 95% (5% increments)
phase unbalance deviation between any two phases percentage of nominal line voltage preset by dip switches. range 5% to 40% (5% increments)
phase reversal any two phases become reversed for the selected delay.
voltage phase loss less than 50% of the nominal line voltage detected.
current phase loss smallest phase current is less than 1/16 of the largest phase current.
there are applications in which is desirable to use an uninterruptable power supply (ups) to provide backup power for metering. this is particularly true for the monitoring of critical loads via communications. otherwise, it is impossible to tell whether the loss of communications is due to a power problem or a problem with the communications wiring itself. this application note helps specifiy a ups for the iq dp 4000 and the iq analyzer.
