YJJ-3SInsulation oil dielectric strength BDV tester with three cups 80kV 100kV oil bdv tester
Insulating Oil Dielectric Strength BDV Tester oil bdv tester
The insulating oil dielectric strength tester (BDV tester) is a specialized device used to measure the breakdown voltage of liquid insulating media such as transformer oil.
Its core function is to directly and quickly assess the electrical insulation strength of insulating oil and determine whether its insulation performance has deteriorated due to high water content, excessive impurities, or aging.
Used to test the dielectric strength of insulating oil in high-voltage electrical equipment such as transformers and instrument transformers.
Available in single-cup, three-cup, and six-cup configurations; options include LCD or touchscreen interfaces.
Voltage range: 0–80 kV (customizable to 100 kV); selectable voltage rise rates of 2.0, 2.5, 3.0, or 3.5 kV/s (customizable).
English-language models comply with ASTM D1816, ASTM D877, and IEC 60156 standards.
Customization available for Bluetooth and RS-232 interfaces, infrared measurement, and intelligent oil quality analysis functions.
