Voltage protection relay siv lub processor ceev thiab qis zog ua nws lub hauv paus.
Thaum lub hwj chim muab kab muaj over-voltage, under-voltage, lossis theem tsis ua haujlwm,
theem rov qab, lub relay yuav txiav tawm lub voj voog sai thiab muaj kev nyab xeeb kom tsis txhob muaj xwm txheej
tshwm sim los ntawm qhov hluav taws xob tsis zoo uas raug xa mus rau lub davhlau ya nyob twg. Thaum lub zog hluav taws xob
rov qab mus rau tus nqi ib txwm, lub relay yuav tig rau ntawm lub voj voog kom paub tseeb tias
kev ua haujlwm ib txwm ntawm cov khoom siv hluav taws xob kawg hauv qab qhov xwm txheej tsis muaj neeg saib xyuas.
