Hipot Test, is also known as Voltage withstand test, which is divided into two types: power frequency voltage withstand test and DC voltage withstand test. The test voltage of the power frequency withstand voltage test is more than one to several times the rated voltage of the tested equipment, and not less than 1000V. Its […]

Preventive testing is conducted to identify potential hazards of equipment in operation, prevent accidents or equipment damage, and to inspect, test, or monitor equipment. It also includes testing with oil or gas samples to assist factories in better protecting electrical equipment, ensuring safer and smoother electricity use, avoiding power failures, and avoiding losses. However, there

How many degrees can the temperature of an oil immersed transformer not exceed? The insulation level of conventional oil immersed transformers is generally Class A, with a winding temperature limit of 105 ℃, which is also the maximum allowable temperature for operation of oil immersed transformers. Oil immersed transformers generally use Class A insulation level,
