Section 7 - Options
7.1 Passive Harmonic Filter
The passive harmonic filter package is located below the transformer secondary on the left side of the power conditioner. See Figure N to the left. This circuit is bi-directional. It will mitigate odd order harmonic currents originating from the load or the facility. Because passive harmonic filters have a tendency to "sink" harmonics regardless of the source, it is necessary to protect this circuit in the event of excessive odd order harmonic content in the facility electrical system. To
Figure Naccomplish this, the power conditioner provides a circuit breaker on the front panel. Should the facility have excessive odd order harmonics, the
circuit breaker will trip. The circuit breaker may be reset while the power conditioner is operating. Unless the source of excessive harmonic current is located and corrected, the circuit breaker will likely trip again immediately.
NOTE: The CPC series will operate properly and provide power conditioning even if the harmonic mitigation breaker is tripped. The breaker may be reset with power applied to the unit. However, it will be necessary to address the harmonic condition of the facility electrical system if breaker tripping persists.
7.2 Basic Metering
If equipped with this option, a Power Measurements Limited Series 6200 ION compact modular power meter will be installed in the front panel adjacent to the input circuit breaker. The 6200 ION provides energy and demand measurements, per phase voltage, current, frequency and power factor, peak current demand, THD, and other real-time, true RMS electrical parameters. Communications capability is also available. Contact the manufacturer of the power conditioner for more information about optional communications capabilities.
7.3 Power Management
If equipped with this option, the power conditioner will have a Power Measurements Limited Series 7500 ION power monitor installed in the front bezel. The 7500 ION is shown in Figure X. The 7500 ION monitor provides measurement of critical operating parameters such as voltage, current, power factor and demand. It also provides the ability to monitor apparent power, true power, reactive power and to display vector diagrams, harmonic currents and a wealth of other information in either alphanumeric or bar graph formats. The 7500 ION monitor stores waveforms and event logs and makes them available to facilities or systems managers when equipped with one of several optional communications interface cards. Optional communications interfaces include, 10Base-T or 10Base-FL Ethernet, RS-232, RS485, or modem connections. An optical port on the front panel is standard. Contact the manufacturer of the power conditioner for more information about optional communications capabilities.
