1) Nnan jung da ai cable line ni hpe hkap la ai lam hpe jep joi ai lam galaw nna, hkap la ai lam ni hpe ngut kre hkra galaw ra ai.
2) Bat mi jan raitim shata mi n du shi yang wan n-gun yawm mat ai cable ni a matu, bai n-gun n jaw shi yang, shanhte a insulation resistance hpe megohmmeter hte shadawn ra ai. Insulation resistance gaw shawng na chyam dinglik ai record hte shingdaw yang (temperature langai sha hta) 30% n yawm ging ai. N rai yang, DC hpe hkam sharang lu ai voltage hpe chyam yu ra ai. Shata mi jan raitim, laning mi n du shi yang, wan n-gun yawm mat ai cable ni a matu, DC hkam sharang lu ai wan n-gun chyam dinglik ai lam hpe, makawp maga chyam dinglik ai wan n-gun a daw mi hta galaw ra ai.
3) Re-terminal, lapran na matut mahkai lam, shing nrai, nnan bang da ai lapran na matut mahkai lam ni nga ai cable ni a matu, phase shara hpe jep yu ra ai, insulation a n-gun hpe megohmmeter hte shadawn ra ai, hkam sharang lu ai voltage hpe chyam yu ra ai. Test yawng ngut ai hpang she, cable ni hpe bai galaw na ahkang jaw lu na re.
