Maimakon power factor capacitor zai iya a kan bus na tattalin arziki, kungiyar kasa da kuma a kan gaji daidai. Amma haka ya kamata a yi a kan bayanin gurbin da al'adu.
Idan wasu gaji suna fitowa ko suka fitowa ba a kan ido, a wannan lokacin ya kamata a fada capacitor bank ta hanyar feeder na da shi. Wannan tushen ya canza a matsayin branch capacitor bank scheme. Idan capacitor bank ya haɗa da feeder ko branch, bai taimaka wajen kurta gurbin a tattalin arziki mai ban sha'awa.

A wannan tushen, indabubin capacitor bank masu kungiyar gaji suna fitowa da kuma kungiyar gaji. Saboda haka tushen ya ba amincewa ga reactive power amma tushen ya fiye.
Idan an fada capacitor bank a kan har daidai, za a ba amincewa ga reactive power har daidai, saboda haka za a ba amincewa ga tsari na volts, kurta gurbin da kuma kurta tasiri a kan har daidai, amma babu da ake yi ne saboda ya ba tattalin arziki da yake fiye da mafi yawan abubuwa. Dalilin mafi yawan abubuwa shine a wannan lokacin ya kamata a fada capacitor bank da ma'aikatoci da ma'aikatar gaji. Don in kula hakan, ya kamata a fada capacitor bank mai duka a kan tattalin volts mai duka, ba a fada capacitor bank mai kala a kan har daidai. Ba a ba amincewa ga reactive power a kan tattalin arziki ba, amma tushen ya fiye a kan mafi yawan abubuwa da mafi girman tattalin arziki. Saboda haka capacitor bank a kan gaji da kuma a kan tattalin arziki mai ban sha'awa, duk da cewa suna da muhimmanci. Daga cikin tsarin da ke neman, za a yi don biyu.
Capacitor bank zai iya a fada a ∑ HV system, tattalin volts mai duka, feeders da kuma tattalin kasa mai duka.

Kasashen Capacitor Bank na Tattalin Kasa

A kan feeders na tattalin kasa, an fada capacitor banks a kan poles don in kurta reactive power na wannan feeder. Wadannan banks suna haɗa da conductors na overhead feeders a kan poles. An haɗa da capacitor banks a kan poles a kan insulated power cable. Tsarin cable ya kamata a kan rating na volts na tattalin arziki. Tsarin volts na tattalin arziki da ake fada capacitor bank a kan poles, ita ce dari 440 V zuwa 33 KV. Rating na capacitor bank ita ce dari 300 KVAR zuwa MVAR. Capacitor bank a kan poles zai iya a kan fixed unit ko switched unit a kan varying load condition.

EHV Shunt Capacitor

A tattalin volts mai duka, an samun electrical power za a faɗa darasi a kan transmission line. A lokacin da ake faɗa, an samun drop voltage da kaɗan saboda inductive effect na line conductors. Wannan voltage drop zai iya a kurta a kan ∑ HV capacitor bank a kan ∑ HV sub-station. Drop voltage na yanzu ita ce da yake da shi a lokacin da gaji ya ci, saboda haka, capacitor bank an fada a wannan lokacin ya kamata a kan switching control don in kula shi a lokacin da ke bukata.

Substation Capacitor Bank

Idan an samun gaji mai inductive a kan tattalin volts mai duka ko medium, ya kamata a fada capacitor bank da ma'aikatoci a kan substation don in kurta inductive VAR na gaji duka. Wadannan capacitors banks ana kontrola a kan circuit breaker da kuma lightening arrestors. Ana bayar protection scheme tare da protection relays.

Metal Encoder Capacitor Bank

Don kasa da tattalin arziki mai duka, indoor type capacitor banks zai iya a fada. Wadannan capacitor bank suna haɗa da metal cabinet. Wannan design ya fiye da bank ya ba da gudummawa. Inda zai iya amfani da wadannan banks zai iya a guda a kan outdoor bank, saboda ba suka haɗa da yanayi a kan yankin ba.

Kasashen Capacitor Bank na Tattalin Kasa

Kasashen capacitor banks suna haɗa da poles mounted capacitor banks a kan wurin gaji ko a kan tattalin kasa.
Wadannan banks ba su taimaka wajen amincewa ga power factor na tattalin arziki mai ban sha'awa. Wadannan capacitors bank suna fiye da wadannan power capacitors bank. Ba a zama a bayar duk types of protection schemes for capacitor bank a kan pole mounted capacitor bank. Idan pole mounted cap bank ita ce outdoor type, amma yana iya a haɗa da metal enclosure don in kula shi a kan yanayi a kan yankin.

Fixed Capacitor Bank

Akwai wasu gaji mai inductive da ke buƙata fixed reactive power don in amincewa ga power factor. A wannan type feeder, an amfani da fixed capacitor bank. Wadannan banks ba su da separate control system don in switch ON or OFF. Wadannan banks suna run a kan feeders. Banks suna haɗa da feeders a lokacin da feeders suka haɗa.

Switched Capacitor Banks

A tattalin volts mai duka, compensation of reactive power ita ce da ke buƙata a lokacin da gaji ya ci. Ba zan iya a samu karfi idan an haɗa bank a kan tattalin arziki a lokacin da gaji ya ci. A lokacin da gaji ya ci, capacitive effect na bank zai iya sa reactive power na tattalin arziki, ba a kurta ba.
A wannan yanayi, ya kamata a switch ON capacitor banks a lokacin da gaji ya ci da power factor poor, kuma ya kamata a switch OFF a lokacin da gaji ya ci da power factor high. Idan a switch ON capacitor bank, zai iya ba reactive power daɗi da tattalin arziki. Yana taimaka wajen amincewa ga desired power factor na tattalin arziki a lokacin da gaji ya ci. Yana kula over voltage na tattalin arziki a lokacin da gaji ya ci saboda capacitor an kula shi a lokacin da gaji ya ci. A lokacin da ake amfani da bank, yana kurta gurbin a kan feeders da kuma transformer na tattalin arziki saboda an haɗa shi a kan primary power system.
