Kev Piav Qhia Luv:

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 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 tshuab hluav taws xob kawg. Thaum lub zog 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 muaj

ntawm cov khoom siv hluav taws xob kawg nyob rau hauv cov xwm txheej tsis muaj neeg saib xyuas
