1) Lub ntsuas hluav taws xob hauv Circuit Court qhia qhov txawv txav los yog xoom. Yog hais tias tam sim no Circuit Court siv rau kev ntsuas lub 'meter' yog qhib Circuit Court; Yuav ua rau kev nyeem ntawv tsis sib haum ntawm peb-theem ammeters thiab txo qis hauv kev nyeem ntawv fais fab; Lub 'meter' tsis tig los yog qhov nrawm nrawm; Yog tias qhov qhia tau qee zaum ploj lawm; Tej zaum nws yuav nyob rau hauv lub xeev semi-qhib Circuit Court;
2) Seb lub cev CT muaj suab nrov, tsis sib xws kev co, cua sov hnyav, haus luam yeeb thiab lwm yam tshwm sim; Tau kawg, cov xwm txheej no tsis pom tseeb thaum lub sijhawm thauj khoom;
3) CT thib ob Circuit Court terminals thiab tivthaiv hlau hau muaj paug thiab ignition tshwm sim;
4) Kev ua haujlwm tsis raug lossis tsis kam lees kev pov hwm rov qab; Qhov xwm txheej no tuaj yeem kuaj pom thiab daws tau yog tias muaj kev sib tsoo lossis kev tawm mus sab nraud;
5) Lub ntsuas hluav taws xob, relay, thiab lwm yam yog haus luam yeeb thiab hlawv. Thiab lub ntsuas hluav taws xob reactive, hluav taws xob ntsuas hluav taws xob, cov chaw taws teeb tswj cov khoom xa tawm, thiab cov cuab yeej tiv thaiv relay raug hlawv; Tsis tsuas yog nws yuav ua rau ib qho kev qhib hluav taws xob thib ob hauv CT; Nws kuj tseem yuav ua rau qhov luv luv luv luv hauv PT.
Thawj kauj ruam ntawm lub transformer tam sim no yog qhov txhab nrog cov hlau tuab, uas tsuas muaj ib los yog ob peb lem, yog li nws impedance me me heev. Thaum cov kauj ruam tseem ceeb txuas nrog hauv series hauv Circuit Court nyob rau hauv kev sim, qhov hluav taws xob poob ntawm ob qho kawg yog qhov tsawg heev. Txawm hais tias muaj ntau qhov kev hloov pauv hauv ob kauj ruam, nyob rau hauv ib txwm muaj, nws lub zog hluav taws xob E2 tsis siab, tsuas yog hais txog ob peb volts. Tank hom transformer
Qhov tam sim no dhau los ntawm kev thauj khoom los ntawm cov chaw tsim khoom tam sim no transformer yog sib npaug rau cov khoom ntawm qhov ntsuas tam sim no los ntawm cov kauj ruam thib ob thiab qhov hloov pauv tam sim no. Yog hais tias lub ammeter yog siv ua ke nrog ib tug tshwj xeeb tam sim no transformer, lub teev ntawm ammeter no yuav raug cim raws li tus nqi tam sim no nyob rau hauv lub high tam sim no Circuit Court.
Qhov thib ob tam sim no Z ntawm tam sim no transformer feem ntau yog tsim nrog tus qauv tus nqi ntawm 5A. Tam sim no transformers siv nyob rau hauv circuits nrog txawv tam sim no sib txawv, thiab lawv conversion ratios muaj xws li 10/5, 20/5, 30/5, 50/5, 75/5, 100/5, thiab hais txog. Cov saum toj no yog qee qhov kev ua haujlwm ntawm cov transformers tam sim no. Rau kev nyab xeeb vim li cas, ib qho kawg ntawm lub kauj kauj ruam thib ob ntawm lub tshuab hloov tam sim no thiab lub plhaub hlau yuav tsum tau muab tso rau hauv av.
