📢 Why Are These Tests Important?
⚡ Megger Test: Cable insulation ki basic condition check karta hai.
⚡ VLF Test: High voltage cables ka insulation check karne ke liye low-frequency AC voltage use karta hai.
⚡ Partial Discharge Test: Cable ke andar hidden insulation faults detect karne ke liye hota hai.
⚡ Tan Delta Test: Cable insulation ka aging effect aur dielectric loss analyze karne ke liye hota hai.
⚠️ Important Safety Tips:
⚡ Testing se pehle power source disconnect karna na bhoolen.
⚡ Testing ke dauraan proper PPE (Personal Protective Equipment) use karein.
⚡ Megger ki proper rating choose karein jo aapki cable ke voltage level ke according ho.
