Máy kiểm tra chỉ số BDV dầu được dùng để làm gì? Và cách sử dụng như thế nào?
Đọc thêmwhat’s the oil bdv tester is uesd for? An oil BDV (Breakdown Voltage) tester is used to measure the dielectric strength of insulating oils, typically in transformers and other electrical equipment. It determines how well the oil can withstand electrical stress without breaking down. A higher breakdown voltage indicates better insulating properties, which is crucial […]
