The lightning protection component tester is an instrument suitable for testing the DC parameters of overvoltage protection components of zinc oxide lightning arresters (zinc oxide valve plates and varistors). It has functions such as memory, computation, retention, self checking, and leak alarm. The KEFLY-2G lightning protection component tester has functions such as high voltage short-circuit protection, overcurrent protection, and high voltage pre setting. The high-pressure self release time is less than 5 seconds. The test results are displayed by two 31/2LCD digital displays, one displaying voltage value and the other displaying current value, with high accuracy and good reliability. Can be used as an adjustable DC high voltage source (1kV~10kV) with an output current of ≤ 1mA.
1、 Performance characteristics
1. The KEFLY-2G lightning protection component tester is suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide lightning arresters (varistors), metal ceramic two - and three electrode discharge tubes, and vacuum lightning arresters. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.
2. It has functions such as high voltage short-circuit protection, overcurrent protection, high voltage preset, and range adjustment, with a high voltage self discharge time of less than 0.5 seconds.
3. It has a self checking function.
4. The measurement data is displayed by a three and a half digit LCD digital display, with high accuracy and good reliability.
5. During measurement, the range can be pre-set and an audible prompt can be issued for exceeding the range during the measurement process, which is suitable for device grouping and inspection discrimination.
6. Choosing continuous measurement allows for uninterrupted testing of batch samples.
7. The panel has simple functions and is easy to operate.
8. The lightning protection component tester is lightweight and easy to carry.
