Q: Kuv tus megger muaj 500V, 1000V, 2500V, 5000V, thiab 10kV. Kuv yuav xaiv qhov twg rau LV, MV, thiab HV?
A: Kev siv hluav taws xob tsawg dhau yuav tsis cuam tshuam kev rwb thaiv tsev. Ntau dhau tuaj yeem ua rau muaj kev puas tsuaj loj - los ntawm. Ua raws li lub rooj sib txuam.
Standard DC Test Voltage Xaiv:
| Cable ntsuas hluav taws xob (U0 / U) | Rwb thaiv tsev Class | Pom zoo DC Test Voltage | Kev Nyab Xeeb Limit (Max) |
| Tsawg Voltage (LV) <0.6/1 kV | Tsawg voltage | 500V rau 1000V DC | 1000V DC fais fab mov |
| Nruab nrab Voltage (MV) 6/10 txog 20/35 kV | Nruab nrab voltage | 2500V lossis 5000V DC | 5000V DC fais fab mov |
| Cov hluav taws xob siab (HV) 66 txog 220 kV + | High Voltage | 5000V lossis 10,000V DC | 10,000V DC |
Vim li cas thiaj siv DC rau IR? Ib qho khoom siv DC tsis tu ncua kos cov khoom siv hluav taws xob tam sim no tom qab thawj ob peb feeb, tso cai rau kev ntsuas qhov me me tiv thaiv tam sim no (micro{0}}amps) ntws los ntawm kev rwb thaiv tsev.
