MCE ADV – کنترلر توان راکتیو استاندارد

Description

Power factor controllers MCE-6 ADV (6 steps) and MCE-12 ADV (12 steps) measure the cos φ of a supply system and control the automatic connection and disconnection of compensation capacitors, according to desired cos φ.

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. MCE ADV 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.

FEATURES

1. Improved setting up configuration when commissioning

Phase
Installation and polarity of the CT (Current Transformer). This controller avoids user to switch phases and polarity (cabling) of CT (X/5) connection. Now, user can adjust it and set it up through display menu on the MCE ADV; indicating what phase it is installed and the polarity of the CT.

2. Values/measures in the network

– Current (A)
Total RMS current (A) measured from the CT (X/5).
– Voltage (V)
Phase RMS voltage (V) measured from the capacitor bank
main copper bars.
– THD (%) in Current (A)
Current (A) Harmonic distortion (%) in the network.
– MAX (A) & (V) Recording
MCE ADV is recording the maximum phase current and voltage values measured from the CT (X/5) connection and from the capacitor bank main copper bars, respectively.

3. Event Alarms by LED and Relay

MCE ADV comes with alarm events warnings, whether by LED or RELAY, in case of these circumstances:
– Lack of compensation
– Over-compensation
– Over-voltage
– Over-current
– CT unplugged
– Current below the limits

(Note: to perform alarm relay, there must be available at least one step relay)
