The fault recorder screen is mainly used to record the change process of electrical quantity of line fault and abnormal operation, which provides reliable basis for analyzing fault, handling accident and analyzing action behavior of relay protection device.

Requirements of fault recorder for use place:

1. There should be no explosive medium in the place of use. The surrounding media should not contain gas and conductive medium that corrode metal and damage insulation. It is not allowed to be filled with water vapor and have serious mold;

2. The place of use should be equipped with facilities to prevent rain, snow, wind and sand, as well as anti-static measures;

3. The location of the site should be away from the area with high fire risk, as well as the place where dust, oil fume, harmful gas source and corrosive, flammable and explosive materials are stored. Avoid low-lying, humid, thunder, heavy salt damage areas and places with frequent earthquakes; avoid strong vibration sources and strong noise sources; avoid strong electromagnetic field interference; avoid high-rise buildings or basements, as well as the lower or next door of water equipment.

The extreme limits of ambient temperature of fault recorder are - 25 ℃ and 70 ℃. The equipment without excitation should be able to withstand the temperature in this range without irreversible damage. After the temperature is recovered, the fault recorder can work normally.

These are the requirements of the place where the fault recorder screen is used and the ambient temperature, which should be paid attention to and remembered by the field staff. At the same time, it is necessary to correctly understand the basic principle and characteristics of the fault recording device, and master the fault types and treatment methods of the device in operation, which is a powerful guarantee to ensure that the device is always in good working condition.
