Cov khoom siv ntsuas hluav taws xob thib ob muaj ntau haiv neeg thiab feem ntau yog siv los xyuas kom meej qhov tseeb, txhim khu kev qha, thiab kev nyab xeeb ntawm kev ua haujlwm thib ob hauv cov tshuab hluav taws xob. Cov hauv qab no yog qee yam khoom siv thiab lawv txoj haujlwm:
Relay Protection Tester: Qhov no yog cov cuab yeej tseem ceeb rau kev ntsuas hluav taws xob thib ob. Nws tuaj yeem simulate ntau yam kev ua txhaum cai (xws li overcurrent, overvoltage, kev tiv thaiv sib txawv, thiab lwm yam) los ntsuas qhov kev khiav hauj lwm qhov tseem ceeb, rov qab qhov tseem ceeb, lub sij hawm ua haujlwm, thiab kev ua haujlwm ntawm cov khoom siv tiv thaiv, thiab xyuas qhov tseeb ntawm kev xaim hluav taws xob.
Instrument Transformer Yam ntxwv Test Equipment:
CT Analyzer/Voltage-Ampere Characteristic Tester: Ntsuas cov yam ntxwv ntawm kev ua kom zoo, qhov sib piv, polarity, qhov sib txawv ntawm qhov sib txawv, thiab theem sib txawv ntawm cov transformers tam sim no kom ntseeg tau tias lawv ua tau raws li kev tiv thaiv thiab kev ntsuas.
PT / CT Ratio Tester: Ceev ceev ntsuas qhov piv ntawm voltage lossis tam sim no transformers.
Instrument Transformer Polarity Verifier: Ib qho cuab yeej tshwj xeeb siv los tshawb xyuas qhov polarity ntawm CTs lossis PTs.
Secondary Voltage Drop and Load Tester: Siv los ntsuas qhov voltage poob ntawm qhov thib ob Circuit Court ntawm voltage transformers (PTs) thiab qhov tseeb load ntawm lub thib ob Circuit Court ntawm tam sim no transformers (CTs), ntsuam xyuas lub zog metering yuam kev. Txhawb kev ntsuas online yam tsis muaj hluav taws xob cuam tshuam.
Loop Resistance Tester: Siv los ntsuas qhov kev sib cuag ntawm cov hluav taws xob hluav taws xob xws li siab -voltage switches thiab circuit breaker contacts, kom ntseeg tau tias cov khoom sib txuas zoo thiab tiv thaiv overheating faults.
Basic General Instruments:
Multimeter: ntsuas voltage, tam sim no, thiab tsis kam; siv rau kev kuaj xyuas txuas ntxiv mus.
Clamp-ntawm Ammeter: Tsis yog-kev ntsuas tam sim no, haum rau kev ua haujlwm hauv circuits.
Rwb thaiv tsev Resistance Tester (Megohmmeter): Tshawb xyuas cov rwb thaiv tsev tiv thaiv ntawm cov conductors lossis hauv av, tiv thaiv kev luv luv.
Ground Resistance Tester: Ntsuas qhov tsis kam ntawm cov khoom siv hauv av, ua kom muaj kev nyab xeeb hauv av.
Dedicated Equipment rau Digital Substations:
Network Message Analyzer: Siv nyob rau hauv IEC 61850 digital substations los txheeb xyuas SV, GOOSE, MMS, thiab lwm yam kev sib txuas lus los txheeb xyuas qhov tseeb ntawm virtual loops.
