EMK series Capacitor bank components Fig. 4-3 shows the different models of EMK static capacitor banks and their essential components. Note that some protection elements are optional and others may be replaced with equivalent models or adapted to the specific application. -
Page 9: Fast Regulator
EMK series From the electrical standpoint, the unit is made up of the following blocks: 4.6.1 Fast regulator Static capacitor banks are equipped with computer Max f, computer Smart f or computer Plus TF fast regulators. The outputs of these regulators are static; that is to say, instead of an output via relay contact they have a semiconductor-based switch which allows them to perform operations in rapid succession, practically every network cycle. -
Page 10: Installation
INSTALLATION Preparation The CIRCUTOR EMK static capacitor banks are prepared for an easy installation and start-up. Remove the equipment's packaging and verify that the unit's electrical features are suitable for connection to the grid at the site to be installed. For this, check the features label located inside the cabinet, next to the regulator, refer to Fig. -
Page 11: Power Circuit
EMK series 5.3.1 Power circuit • Connect input terminals L1, L2 and L3 (power circuit supply) to the grid using proper sized cables in accordance with the National Electric Code or LVD. Generally, the phase cables use the following colour code: L1 (black), L2 (brown), L3 (grey). If a 230 V auxiliary voltage is required, we can use an internal 400V/230V transformer or use the neutral and connect it to terminal N (blue colour cable). - Page 12 EMK series • The rated current of the CT primary winding must be equal to or slightly greater than the size of the installation's main switch. The CT must be able to measure the maximum forecast current expected to be consumed by all the loads.

Page 13: Static Capacitor Bank Start-Up
EMK series STATIC CAPACITOR BANK START-UP Before start-up The static capacitor banks include a power factor regulator. In order to perform the proper start-up adjustments, the basics of operation of such regulator must be known. For this reason, all capacitor banks come with the specific manual of the regulator used. Find this manual and have it available for the start-up process. -
Page 14: Tests Once The Capacitor Bank Is Connected And The Regulator Has Been Adjusted
EMK series • Once ensured that the regulator is properly connected, adjust the regulator parameters for the installation you are attempting to compensate. For this, follow the instructions of the particular PF regulator manual, supplied with the equipment. Tests once the capacitor bank is connected and the regulator has been adjusted •... -
