MY2012 ultra-low frequency AC high voltage test device

Product Introduction:

The high-voltage withstand voltage test of electrical equipment is one of the most important items specified in the "Insulation Preventive Test". Voltage withstand test can be divided into AC voltage withstand test and DC voltage withstand test. AC voltage withstand test can also be divided into power frequency, frequency conversion, and 0.1Hz ultra-low frequency testing technology. Among them, 0.1Hz ultra-low frequency technology is the technology recommended by the current Electrical Commission.
new generationMY1012 series 0.1HZ ultra-low frequency AC high voltage test deviceIt is the core product independently developed by our company, which overcomes many disadvantages of the * generation mechanical products and has a much higher cost-effectiveness than similar imported products. It is particularly suitable for voltage withstand testing of electrical equipment with high insulation equivalent capacitance (such as power cables, power capacitors, large and medium-sized generators and motors, etc.), and meets the requirements of the newly issued national power industry standard "General Technical Conditions for Ultra Low Frequency High Voltage Generators DL/T849.4-2004" in 2004.
