BDV Oil Test Set
BDV (Breakdown Voltage) Oil Test Set is an equipment used for measuring the breakdown voltage of insulating oils, such as transformer oil, which is used in electrical equipment to insulate and cool electrical conductors. The breakdown voltage is the voltage at which the oil breaks down and allows electrical current to flow through it. This is an important parameter for assessing the quality and effectiveness of the insulating oil.
The BDV Oil Test Set typically consists of a high-voltage transformer, an electrode assembly, a measuring circuit, and a display unit. The high-voltage transformer generates a high voltage (usually up to 100 kV) that is applied to the electrode assembly immersed in the oil sample. The voltage is gradually increased until the oil breaks down, and the voltage at which this happens is measured and displayed on the unit.
BDV Oil Test Set is widely used in the power industry, particularly in transformer maintenance and testing, to ensure the reliability and safety of electrical equipment. The test results can indicate if the oil has degraded or if there are impurities present that may affect its insulating properties.
A typical BDV Oil Test Set consists of the following components:
High-voltage transformer - capable of generating up to 100 kV AC voltage.
Electrode assembly - typically consists of two cylindrical electrodes (one grounded and one high-voltage) that are placed in the oil sample for testing.
Measuring circuit - this circuit is designed to measure the current that flows through the oil sample as the voltage is gradually increased.
Display unit - displays the breakdown voltage of the oil sample in kV.
The technical specifications of a BDV Oil Test Set can vary depending on the Requirment of Clients, but the following are some general technical specifications that you might expect to see:
Input voltage - typically 220V AC or 110V AC, depending on the region.
Output voltage - up to 100 kV AC, adjustable in steps of 1 kV or less.
Test cell - typically a 2.5 mm or 4 mm gap between the electrodes.
Measuring range - typically 0-100 kV, with a resolution of 0.1 kV.
Measuring accuracy - typically +/- 1% or better.
Test duration - typically less than 10 minutes for a full test.
Safety features - such as overvoltage protection, short circuit protection, and safety interlocks.
