FRAKO Germany Power Capacitors enclosed in a Sheet Metal Enclosure with Busbar and Cable entry arrangement for easy cable connection.

LIMITATIONS Capacitor Banks needs to be switched ON & OFF manually using a proper Switching Devices. Inrush Current of the Capacitor Banks needs to be considered for selection.

CAPACITOR BANKS WITH PROTECTION MCB:

FRAKO Germany Power Capacitors along with MCB for Protection Purpose enclosed in a Sheet Metal Enclosure with Busbar and Cable entry arrangement for easy cable connection.

Capacitor application Breaker needs to have faster opening time to avoid restriking between the contacts.  In the case of MCB, the opening time by the tripping mechanism is independent of the operation. 

The present generations MCBs are built-in with current limiting features, thus partially damping the inrush current. 

LIMITATIONS:

• Capacitor Banks needs to be switched ON & OFF manually using a proper Switching Devices.
• Inrush Current of the parallel connected Capacitors needs to be considered for selection.

APPLICATION:

Capacitor Banks can be selected for the Load Centre with several inductive loads operated together where :

• Loading Pattern is constant.
• Level of Harmonics is within the Guidelines for Harmonics.
• Cable size not suitable to connect Individual Capacitors.

MANUAL SWITCHED BANKED CAPACITORS

FRAKO Germany Power Capacitors along with MCB for protection purpose, Capacitor Duty Contactor and ON & OFF Push Buttons for Switching the Capacitors enclosed in a Sheet Metal Enclosure with Busbar and Cable entry arrangement for easy cable connection.

Capacitor Duty Contactors

The Contactors being the only moving Component, necessitates careful selection for this application to ensure longer life for these Contactors.  Due to the characteristics of the capacitor operations and necessity to restrict the inrush current by using a suitable Damping Resistor which shall be in the circuit only for a short duration (during the in-rush current phenomena), a careful selection of the Capacitor Duty Contactors with built-in Damping Resistors is required, considering the Transformer Impedance and the number of Capacitors operating in parallel.

Capacitor Duty Contactors, which has two sets of Contacts, one for restricting inrush current and other set is for continuous loading of the capacitors.  This Capacitor Duty Contactor is specially designed with the Damping Resistance which restricts the inrush current.  We will be using specially designed Capacitor Duty Contactors with Damping Resistors.  These types of Contactors are different from standard contactors.

LIMITATIONS

• Capacitor Banks needs to be switched ON & OFF depending on the requirement of Reactive Power Compensation at that instant manually.
  
  

AUTO SWITCHED BANKED CAPACITORS

FRAKO Germany Power Capacitors along with MCB for protection purpose, Capacitor Duty Contactor and ON & OFF Push Buttons, Auto Manual Selector Switch, Timers for Discharge Interlocks and Control Contactors for Switching ON & OFF the capacitors either in Auto Mode or in Manual Mode enclosed in a Sheet Metal Enclosure with Busbar and Cable entry arrangement for easy cable connection.

In automatic switching, the capacitor Bank is switched through control contactor energized through the motor controls and switched after a fixed delay.  The switching is done through capacitor duty contactors, and push buttons.
