Power factor controllers MCE ADV
Power factor controllers MCE-6 ADV (6 steps) and MCE-12 ADV (12 steps) are designed to measure the requirements of reactive energy of an installation and give the orders of connection and disconnection of capacitors so as to keep the set up cos φ.
Plug and Play
When a power factor controller is installed, a number of parameters need to be set up for a proper operation. Some of these parameters might be hard to know, such as, for example, the voltage phases or the correspondence of the measured current with its voltage, as well as the current transformer ratio. Controller MCE ADV incorporates a smart automatic process that detects the necessary parameters, such as:
- C/K: calculates the ratio of the current transformer and the power of the smallest step.
- Phase: Identifies the voltage sequence and correspondence with the current. In other words, it identifies the UL1, UL2, UL3, when the current measured is IL1, IL2, IL3 and whether it has been connected in the opposite way.
- Number of stages installed and Program: by sequential connection of all steps it finds out how many steps are installed and then calculates the program, i.e., the power ratio between capacitors.
- IMPROVED SETTING UP FOR COMMISSIONING
Installation and polarity of the CT (Current Transformer). The controller allows the user not to have to change phase location where the TC (X/5) is located and/or the reading direction/polarity. The adjustment can be made via the menu on the controller display.
- READING OF INSTALLATION VALUES
- Current (A)
Total RMS current (A) measured from the CT (X/5).
- Voltage (V)
RMS voltage (V).
- THD (%) in Current (A)
Instantaneous harmonic distortion indicative of current present in the installation in %.
- MAX (A) & (V) Recording
It records in memory the maximum system current and voltage values, starting from TC (X/5) and the capacitor bank voltage.
- EVENTS ALARMS BY LED AND RELAY
MCE ADV incorporates a LED and an output relay to warn in case that any of the following circumstances happens:
- Lack of compensation.
- CT unplugged.
- Current below the limits.
(Note: to perform alarm relay it is necessary to have available one step relay).
