Handheld Dual -End Ground Loop Resistance Tester

Handheld DC Loop Resistance Tester

MOEORW-W5020TBS handheld loop resistance tester yog tsim los ua raws li Tuam Tshoj tus qauv kev lag luam fais fabDL/T845.4-2019, tsim los rau siab -precision DC voj tsis kam ntsuas ntawm siab -voltage circuit breakers thiab switchgear. Cov qauv tsim tshiab txhawb nqa ib qho - sab thiab ob npaug - sab hauv av kuaj yam tsis muaj kev cuam tshuam ntawm lub ntiaj teb busbars, tshem tawm cov kev pheej hmoo hluav taws xob uas raug cuam tshuam los ntawm kev dag ntxias thaum lub sij hawm tu. Nruab nrog ua -nyob rau hauv rechargeable lithium roj teeb thiab wireless clamp 'meter' txhawb tsis yog- tiv tauj DC tam sim no tau, cov cuab yeej paub ib txwm plaub- xov hlau kuaj thiab ntse shunt ntsuas, drastic shortening ntawm - qhov chaw kuaj workload rau fais fab tuag tes hauj lwm & txij nkawm departments.}voltage{10} 7-inch siab-brightness xim kov LCD nrog lub hnub ci- nyeem tau cov zaub, siab- ceev MCU centralized tswj thiab ntau theem kev ruaj ntseg tiv thaiv Circuit Court, muaj qhov ruaj khov ntsuas qhov tseeb thiab ua tiav cov ntaub ntawv khaws cia & xa tawm ua haujlwm nrog lub suab tshwm sim tom qab txhua lub voj voog ntsuas.

Tus tester npog plaub lub hauv paus ntsuas kev ywj pheej faib ua ob hom kev sim loj:

1. Ib txwm Loop Resistance hom: Standard plaub-hlau DC tsis kam kuaj. Tshem tawm earthing busbar ntawm ib sab ntawm cov khoom kuaj; Txhaj DC tam sim no I₁ ntawm I + / I - terminals, sau qhov voltage poob V hla cov khoom kuaj ntawm V + / V- terminals, xam qhov tsis kam:R=V/I₁rau Ohm txoj cai.

2. Intelligent Test Mode (Tsis muaj Earthing Busbar Tshem Tawm)

1. Direct Clamp Ntsuas: Wireless clamp captures tiag tiag voj tam sim no I₀ bypassing parallel earthing ceg, xam R=V/I₀.

2. Tib -Sided Shunt Test: Tib wireless clamp ntsuas shunt ceg tam sim no I₂, siv tau kev khiav hauj lwm tam sim no I₀=I₁-I₂, Rx=V/(I₁-I₂).

3. Ob -Sided Shunt Test: Dual wireless clamps sau ob-txoj kev shunt tam sim no I₂₁ & I₂₂, siv tau lub voj tam sim no I₀=I₁-I₂₁-I₂₂, Rx=V/(I₁{5}}I₁{5}I.

Qhov kev xeem ua tiav suav nroglub ntsiab tester chav + wireless Hall- cuam tshuam DC clamp meters (1# CT1,2# CT2).

Wireless Clamp Meter Structure

• Zero- calibration khawm: Pib dua clamp meter xoom drift ua ntej ntsuas; · Lub hwj chim yuam sij: Kev ywj pheej hwj chim tswj rau wireless CT; · LCD npo: tiag - lub sij hawm seem roj teeb, ntsuas DC tam sim no tus nqi thiab CT serial tooj zaub; · Clamp lub puab tsaig: Φ68mm puab txoj kab uas hla rau cable clamping, forward tam sim no inflow polarines.
