Wannan shi ne mota wanda ake yi ba a bukatar mechanical load. A canza field winding’s excitation. Reactive volt ampere zai iya a ambaci ko a fito da synchronous condenser.

Don haɗa power factor da yake da 500 KVAR, ana fiye da synchronous condenser a kan static condenser.

Don systems da yake da rating da ƙarin, an amfani da capacitor bank.          

4). Yadda ake karkashin fuse da circuit breaker?

5). Maimakon tariff?

Tariff tana nufin adadin da ake kasa a kan abubuwa da ake importa daga kasashen maza-maza don haɗa take ci. Saboda haka, yanayin abubuwa za a ƙara da take ci da ma ake so a matsayin abubuwan da ake da a kasar. Tariffs suna amfani a kan haɗa commerce daga kasashen maza-maza ko a kan haɗa imports wa wani abubuwa.

Gwamnati tana kasa duwatsu da tarif:

• Tariff Specification

• Ad-valorem Tariff

6). Yadda ake karkashin transmission & distribution line?

Transmission lines suna amfani a kan yankunan da ke da ƙarin lokaci da suka da voltage da ƙarin don kawo energy da ƙarin. Duka haka, transmission line tana kawo energy daga power plants zuwa substations.

Distribution lines suna kawo energy a kan yankunan da ke da ƙarin lokaci. Suna kawo energy a kan yankunan saboda voltage da ke da ƙarin. Substation tana kawo energy zuwa gidajen mutanen.

7). Me koyar da sadarwa na energy sources?

Akwai koyar da sadarwa na energy sources,

• Renewable Energy Source

• Non-Renewable Energy Source

 wadanda suke koyar da:

Renewable Energy Source – Sadarwa na energy suna cika daga sasar da ke da zamani da ake tafiya.

Misalai na renewable sources:

• Solar energy

• Wind energy

• Geothermal energy

• Water energy

• Biomass and biofuelsenergy

Non-Renewable Energy Source-Sadarwa na energy suna cika daga sasar da ba zan iya a tafiya ba kuma zai lafiya a lokacin da ƙarin. Non-renewableenergy sourceincludes

• Oil

• Coal

• Petroleum and

• Natural Gas

8). Maimakon relay?

Switches da suke kisa da karo circuit suna kiran relays. Suke yi wannan aiki a kan electrical da electromechanical. Relays suna amfani a fannon da dama, kamar manufacturing. Don kontrol energy, control panels & building automation suna amfani.

Relay Types:Relays suna koyar da koyar da sadarwa a kan operating principles. polarity and operation:

• Electromechanical Relay

• Solid State Relay

• Electrothermal Relay

• Electromagnetic relay

• Hybrid Relay

9). Maimakon nuclear power plant?

Nuclear power plants suna amfani da nuclear fission don samun energy. Nuclear reactors da Rankine cycle (wanda ke convert water into steam) suna amfani don samun heat. Wannan steam tana da take ciki a kawo turbine & generator. Nuclear power tana da 11% na total global electricity production.

Wadannan su ne abubuwan da ake amfani a cikin nuclear power reactors don samun energy.

• Steam Generation

• Nuclear Reactor

• Turbine & Generator

• Water Cooling Towers

10). Maimakon cable grading ko grading of cables?

Kalmomin "grading of cable" tana nufin process da ake yi don samun distribution daidai na dielectric stress (or) voltage gradient a cikin dielectric. Dielectric stress tana da take da ƙarin a outermost sheath da conductor, kuma tana da take da ƙarin a surface.

Saboda tension ba tana da take da daidai a cikin cable ba, insulation tana lafiya da take ci, wanda tana haɗa cable da take da ƙarin. Grading of cables tana haɗa uniform distribution daidai na dielectric stress, wanda tana haɗa wannan problem.

11). Maimakon pumped storage plant?

Pumped-storage  hydroelectricity, kuma ake kira hydroelectricity, tana da wata type da hydroelectric energy storage da ake amfani don load balancing. Idan akwai talabukar da ƙarin da energy, ake kasa ruwa daga reservoir through turbines don samun energy. Tana da ƙarin capacity available for the grid.

12). Yadda ake verify current transformer(CT)?

A digital multimeter equipped with a millivolt AC (mVac) range may be used to evaluate the output voltage (Vo) of a current transformer (CT) out in the field. This test is helpful for confirming that the CT is functioning correctly that current flows through the conductor on which the CT is mounted.

13). Maimakon ACSR?

ACSR – Aluminium Conductor Steel-Reinforced Cable

Kalmomin "aluminium conductor steel-reinforced cable" (ACSR) tana nufin wata type da stranded conductor da tana da ƙarin capacity da ƙarin strength da ake amfani a overhead power lines. Aluminium da ƙarin purity tana da take da outer strands saboda conductivity, ƙarin weight, ƙarin cost, resistance to corrosion, and reasonable mechanical stress resistance.

14). Bayyana Ferranti effect

Voltage increases a cikin transmission lines da receiver end compared to the  sending end voltage tana kiran ferranti effect. Ana samun shi idan ba ake kasa load ko ake kasa ƙarin load ba.
