LIFASA MASTER VAR Controller:
  • Measurement with three current transformers guarantees an analogue reading of the company’s meter.
  • The Master control Var reactive energy regulator is the only regulator in the market that offers the possibility of using 3 measuring transformers in addition to the traditional method of measuring with a single current transformer, as well as providing the functions of an integral power analyzer and controlling the residual leakage currents.
 
  • Master control Var is a regulator that guarantees excellent preventive maintenance operations by means of programming its alarms and the test options of the capacitor status, offering the maximum supervision and safety of your compensation unit.
 
The Controller MASTER control VAR is a reactive energy regulator unit that measures the cos φ of the grid and that regulates the connection and disconnection of capacitors in order to correct it.
 
In addition to the basic functions of any regulator, the Controller MASTER control VAR:
  •  Performs the functions of a network analyzer, measuring and viewing multiple parameters.
  • Has a Plug&Play function for automatic configuration of the device.
  • Has an AutoTest and manual test function for testing the status of the capacitors of the ca- pacitor bank.
  • Has an FCP system, which minimises the number of connections and disconnections of the relays.
  • Supports step forcing.
  • Can work with various connection types.
  • Measures leakage current with the option of associating an alarm and conducting a search for and cancelling the faulty capacitor.
  • Has multiple alarms for warning of possible faults, whether in the capacitor bank or in the installation.

    Application

    The connection of 1 or 3 transformers makes Master control Var the perfect regulator in any installation, allowing the following:

    1. Changing from 1 to 3 transformers in following cases: - Changes in reactive energy penalties : -Changes in consumption habits , - significant imbalances in the system
    2. Replacing the regulator of any capacitor bank
    3. Perfect for installations with up to 4 objective cos, since it can adapt to any compensation need (different time periods).
    4. It can be used with Medium Voltage compensation units.

    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. MASTER 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.
