The purpose of this manual is to assist during the installation, start-up and maintenance of OPTIM HYB series low voltage (LV) capacitor banks with static operation. Carefully read the manual to achieve the best performance from those units. 2.1.- CAPACITOR BANK COMPONENTS From the electrical standpoint, the unit is made up of the following blocks:
The document describes the procedure to perform preventive maintenance on capacitor banks. The procedure includes identifying the equipment, performing a general cleaning, checking the electrical connections, checking the condition of the components, and testing operation before putting them back into service.
The theory of operation is that any unbalance, of the system or the capacitor bank, will shift the neutral and reflect as the residual voltage across the open delta and can be used for the protective scheme. The unbalance voltage across the open delta in the event of failure of a unit in any series group can be expressed by
There are many studies on the failure modes of electrolytic capacitors, and mainly aluminum electrolytic capacitors. Indeed, from the understanding of the mechanisms and failure modes of a capacitor, it is possible to apply a maintenance in order to know the remaining lifetime of the component.
To the production and inspection of the capacitors, the standards (VDE [German Association for the Electrical, Electronic, andInformation Technologies] and IEC provisions and requirements) that, unless otherwise explicitly agreed upon by the parties, are effective at the time of the order confirmation will apply.
The procedure includes identifying the equipment, performing a general cleaning, checking the electrical connections, checking the condition of the components, and testing operation before putting them back into service. The objective is to identify possible faults and ensure that the capacitor banks are working correctly.
Mechanisms and failure modes according to the stress in an electrolytic capacitor. A normal use of the capacitor leads to the evaporation of the electrolyte and the repair of the oxide layer. These are two causes of electrolyte disappearance, which is the main cause of capacitor degradation under normal conditions.
