Kabo ea Matla
E fetisetsa matla a -voltage e tlase (mohlala, 400V/230V) ho tsoa ho transformer ho ea makaleng a fapaneng, e fana ka meroalo e kang mabone, li-motor, le sockets.
Taolo ea Potoloho
Ka bowena kapa ka tsela e iketsang e laola potoloho ho/tima (mohlala, ho qala/ho emisa ha enjene, ho khantšoa ha potoloho ea mabone) ka likarolo tse joalo ka li-circuit breaker le likhokahano.
Tšireletso ea Tsamaiso
- -Tsireletso ea Potoloho e Khutšoanyane: Sekhechana sa potoloho se tsamaea hang-hang 'me se sitisa lebelo la nako ha ho ka ba le potoloho e khutšoane.
- Tšireletso ea ho Feta ho Fetisisa: Relay ea mocheso kapa yuniti ea maeto ea elektroniki e behang lintho tse ngata morao tjena le maeto ka tieho ea nako.
- Tšireletso ea Leakage: Sesebelisoa se setseng sa hona joale (RCD) se lemoha ho lutla ha hona joale ebe se khaola potoloho.
- Tšireletso ea Undervoltage / Overvoltage: Relay ea motlakase e lemoha ho se lekane ha motlakase le maeto.
Tlhokomelo le Metara
Li-ammeter, li-voltmeter, le metha ea matla li fana ka tlhahlobo ea nako ea sebele-ea lipharamitha tsa motlakase (mohlala, current, voltage, power factor, le tšebeliso ea matla).
Matšeliso a Reactive Power (Ha ho boikhethelo)
Libanka tsa Capacitor (joalo ka letoto la GGJ) li fana ka matšeliso a matla le ho fokotsa tahlehelo ea mela.
