MC-330A-100/200V is a special AC high voltage transient testing device. It is suitable for testing mains power distribution cable, insulation, overload capacity, lightning surge overvoltage and lightning current of various electrical equipments and installations. It is a full-featured product with a simple operation and low noise.

The application field of MC-330A-100/200V includes laboratory applications, field tests and lightning protection tests. In the laboratory, it can be applied to the voltage withstand test of the insulation of various electrical equipment, the overload capacity test of the cable, and the lightning current test of the electrical equipment and protection measures.

For field tests, it can be used to test and analyze the reliable operation and flashover characteristics of power cables and lines, and be able to test whether the distribution system meets the safety requirements. Also, it can be used for lightning protection tests, such as analysis of lightning protection, Earth resistance, grounding electrode installation position, etc. So that it can be comprehensively measured and protected.

MC-330A-100/200V\'s working principle is based on AC series controlled spark gap. The main circuit is configured by a test transformer and a controlled spark gap. The test transformer is connected to a power source and a controlled spark gap is connected in series. The controlled spark gap is connected to the induction high voltage insertion head. When the frequency is increased, the gap sparking potential is increased, and an arc is produced gradually in the spark gap. Finally, a high voltage is formed at the test voltage, and then connected with the induction head.

The series controlled spark gap also has a built-in voltage stabilizer, which can stabilize the arc burning voltage of the transformer, and the output voltage will not exceed the test rated voltage. This is important for the safety of the testing item. In addition, the arc control knob can adjust the arc strength to keep a stable arc.

With MC-330A-100/200V, the testing items can be fully tested and observed for accuracy and reliability. It is reliable and widely used in power distribution, automation, motor drive, lightning protection, relay protection and other industries. With its simple operation and low noise, MC-330A-100/200V is an ideal tool for AC high voltage transient testing.
