Power factor correction capacitors Clause Samples
The 'Power factor correction capacitors' clause establishes requirements for the installation and use of capacitors designed to improve the power factor in electrical systems. Typically, this clause specifies the technical standards, placement, and maintenance obligations for such capacitors, ensuring they are appropriately sized and safely integrated into the system. By mandating these measures, the clause helps reduce energy losses, lower utility costs, and maintain efficient operation of electrical infrastructure.
Power factor correction capacitors. Power factor correction capacitors shall conform to IS 2834 in all respects. Approval of insurance association of India shall be obtain if called for. Capacitors shall be suitable for 3 phase 415 volts 50 HZ supply and shall be available in single and three phase units of 5,10,15,20,25 and 50 kVAR sizes as per requirements. Capacitor shall be usable for indoor use, permissible overloads being as below. Capacitors shall be hermetically sealed in sturdy corrosion proof sheet steel containers and impregnated with non inflammable synthetic liquid. Every element of each capacitory unit shall be provided with its own built in silvered fuse. Capacitors shall have suitable discharge device to reduce the residual voltage from crest value of the rated voltage to 50 volts or less within one minute after capacitor is disconnected from the source of supply. The loss factor of capacitor shall not exceed 0.005 for capacitors with synthetic impregnates The capacitors shall withstand power frequency test voltage of 2500 volts AC for one minute. Insulation resistance between capacitors terminals and containers when a test voltage of 500 volts DC is applied shall not be less than 50 meg.ohms.
