What is breakdown voltage test ?
Breakdown voltage test is a type of electrical test used to determine the voltage at which an insulating material breaks down and conducts electricity. The test is performed by applying a high voltage to the material under test and increasing the voltage until the material breaks down, indicating its dielectric strength.
Breakdown voltage test is commonly used in the electrical industry to ensure the safety and reliability of electrical equipment, such as transformers, switchgear, and cables. Insulating materials can degrade over time due to factors such as heat, moisture, contamination, and mechanical stress. This can cause the material to lose its dielectric strength and become conductive, leading to electrical faults and equipment failure.
By performing a breakdown voltage test, the dielectric strength of the insulating material can be determined and compared to industry standards and specifications. This helps to ensure that the material is suitable for its intended application and can withstand the electrical stresses it will be subjected to.
Abstract of IEC60156:
* IEC 60156 specifies the method for determining the dielectric breakdown voltage of insulating liquids at power frequency.
* The test procedure is performed in a specified apparatus, where the oil sample is subjected to an increasing AC electrical field until breakdown occurs.
* The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2/s at 40 °C.
* It is appropriate both for acceptance testing on unused liquids at the time of their delivery and for establishing the condition of samples taken in monitoring and maintenance of equipment.
