SF6 gas-insulated equipment is widely used in the electrical power industry due to its excellent insulation and arc-quenching properties. However, moisture can significantly affect the performance and reliability of SF6 gas-insulated equipment. Moisture can cause insulation breakdown and reduce the dielectric strength of SF6 gas, leading to equipment failure. Therefore, accurate measurement and control of moisture levels in SF6 gas-insulated equipment are crucial.
The IEEE Guide for Moisture Measurement and Control in SF6 Gas-Insulated Equipment, IEEE Std. 1125, 1993, provides detailed guidance on moisture measurement and control in SF6 gas-insulated equipment. The guide covers various moisture measurement techniques, such as dew point measurement, chemical analysis, and electronic sensing. It also discusses the effects of moisture on SF6 gas-insulated equipment, including insulation breakdown, reduced dielectric strength, and equipment failure.
WS-2 Dew Point Meter is researched and designed based on IEEE standard by using a high-precision dew point sensor and the latest digital circuit control technology, which is the intelligent precision instrument to measure the moisture content of the SF6 gas
The instrument uses intelligent self-calibration technology, a wide measuring range, fast response, high accuracy, good linearity, and a dynamic display measurement curve. While the instrument with an automatic dryer, can greatly shorten the measuring time.
