Ukusabalalisa Amandla
Isabalalisa amandla-amandla kagesi aphansi (isb, 400V/230V) aphuma ku-transformer kuya emagatsheni ahlukahlukene, ihlinzeka ngemithwalo efana nezibani, amamotho, namasokhethi.
Ukulawulwa Kwesekethe
Ngokuzenzela noma ngokuzenzakalelayo ilawula ukuvala/ukuvula isekethe (isb., ukuqala/ukuma kwenjini, ukushintsha kwesekethe yokukhanyisa) ngokusebenzisa izakhi ezifana nezinqamuli zesekethe nezixhumi.
Ukuvikelwa Kwesistimu
- -Ukuvikelwa Kwesekethe okufushane: I-circuit breaker iyahamba ngokushesha futhi iphazamise umsinga uma kwenzeka isifunda esifushane.
- Ukuvikela Ukulayishwa Okuningi: I-thermal relay noma iyunithi yohambo lwe-elekthronikhi iqapha ukulayisha ngokweqile kwamanje kanye nohambo ngokubambezeleka kwesikhathi.
- Ukuvikela Ukuvuza: Idivayisi yamanje eyinsalela (RCD) ithola ukuvuza kwamanje futhi inqamule isekethe.
- Ukuvikelwa kwe-Undervoltage/Overvoltage: I-voltage relay ithola ukungahambi kahle kwamandla kanye nohambo.
Ukuqapha kanye Ukulinganisa
Ama-ammeter ahlanganisiwe, ama-voltmeter, namamitha wamandla anikeza{0}}ukuqapha kwesikhathi sangempela kwamapharamitha kagesi (isb, i-current, voltage, factor factor, kanye nokusetshenziswa kwamandla).
Isinxephezelo Samandla Asebenzayo (Ongakukhetha)
Amabhange e-Capacitor (njengochungechunge lwe-GGJ) ahlinzeka ngesinxephezelo sesici samandla futhi anciphise ukulahlekelwa kolayini.
