Description

PFCL Elite controller has a built in power analyzer allowing the measurement of main electrical parameters (voltage, current, harmonics, active and reactive power, apparent power, etc.). The device gives a detailed information on both, voltage and current harmonic components. PFCL Elite controller measures also ambient temperature and keeps a record of maximum and minimum values of all measured parameters.

Built-in leakage control

PFCL Elite have a built-in circuit to measure the earth leakage current through a WGC transformer. The regulator is able to measure the individual leakage of each capacitor. This allows to disable a damaged capacitor if an excess of leakage current is detected without interrupting the supply service.

Plug and Play

A series of parameters must be configured when a power factor regulator is installed, to make sure that it operates correctly. Some of these parameters might be hard to know, such as, for example, the voltage phases or the voltage corresponding to the current measured, as well as the current transformer ratio. PFCL Elite has been designed with 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 current. In other words, it identifies the UL1, UL2, UL3, when the current measured is IL1, IL2, IL3 and whether it is connected in the opposite way or not.
• Number of stages installed and Program: the system connects all stages in a sequence, finds out how many stages are installed and then calculates the program, i.e., the power ratio of the capacitors.

Serial Communications

PFCL Elite controllers are equipped with RS-485 communication with MODBUS protocol. This allows the integration of the PF regulator in a data network driven by a computer (PC). Enables data recording, remote control, supervision and preventive maintenance of the PF correction equipment itself and of the whole LV network.

AUTO-ON-OFF Function

This function allows to define the operating mode of each individual capacitor step:

• Automatic mode (Auto).
• Fixed mode (ON): Capacitor is always ON.
• Disconnected mode (OFF). Capacitor is always OFF.

Safety and maintenance

• PFCL Elite performs a capacitor test every time that a capacitor step is switched ON. The real power and the leakage current of each step can be displayed.
• Up to 14 different alarm conditions can be programmed.
• Internal counter register which counts the number of operations of each individual capacitor step
