4.- OPERATION
The
Computer SMART III FAST
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.
The control is carried out in the four quadrants,

In addition to the basic functions of any regulator the Computer SMART III FAST :

Performs the functions of a network analyzer, measuring and displaying multiple parameters.

Has a Plug&Play function for automatic configuration of the unit.

Has an AutoTest and manual Test function for testing the status of the capacitor bank capacitors.

Has an FCP system which minimises the number of capacitor connections and disconnections.

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 installa-
tion.
