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 […]

Máy kiểm tra điện áp cao DC là gì?
Đọc thêmWHAT IS DC HIPOT TESTER ? For medium to high voltage rotating equipment, DC Hipot tests called Step Voltage or Ramp tests are used to see if the start of an insulation breakdown can be detected as the voltage is raised. If a breakdown is starting the test can be terminated before there is an […]
