Installation: The installation of the capacitors should take into account the rules and recommendations of IEC 60831 Standard. The capacitors are for indoor installation away from heat sources and in well ventilated places.
Optimal allocation of shunt capacitors in the radial distribution networks results in both technical and economic benefits. This paper presents a two-stage method of Loss Sensitivity Factor (LSF
medium voltage capacitors installed in the high-voltage and medium-voltage transformer substations. Once Edelnor attained the required power factor and the demand for electricity continued to grow, further investments in power factor correction for the distribution network began showing diminishing returns. Edelnor started to explore the benefits of deploying PFC in

1. Installation: The installation of the capacitors should take into account the rules and recommendations of IEC 60831 Standard. The capacitors are for indoor installation away from heat sources and in well ventilated places. There shall be a minimum distance of 40 mm between capacitor.
The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
There shall be a minimum distance of 40 mm between capacitor. Check that the voltage and frequency given on the capacitor name plate are appropriate for the mains where it is to be installed. Connection cables will be sized for minimum 1.43 times the rated current of the capacitor.
Battery-mounted capacitors should be connected by means of flexible cables or by braids. Thin-film and some small passive components can exhibit sensitivity to Electrostatic Discharge (ESD). ESD charge/discharge voltage can exceed tenth of kilo-Volts and the ESD typical charge current can be around 1 to 10A in many cases.
The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard:
When handling ceramic capacitors, it is important to minimize abrasion and mechanical shock. Taped and reeled components are ideal for direct presentation to the placement machine. Minimize mechanical shock during handling, especially for chip multilayer ceramic capacitors.
