In general, there is no doubt that the power plant and line with high voltage class and large-capacity transportation play a vital role in the electrical network. However, on account of the weak wire tables in country’s electrical power system ,we need to prevent the pollution flashover which can bring the overall system to disintegrate and cause the big- area power cut. Therefore, before design and construction, we should primarily detect the external insulation’s saturated salt density to determine the contamination levels in your area. And then select the appropriate external insulation creepage distance to bring the pollution flashover to an acceptable degree in power system with safe-economical transportation (ie acceptable pollution flashover rate). So, there is a demands of Electricity Industry about the pollution flashover controlling for it can bring down the economic losses to a minimum. Insulator’s Salt Density Measuring Instrument, a dedicated instrument that can detect not only the external insulation’s equivalent salt deposit density but the Conductivity, is frequently used to prevent the pollution flashover in power system. However, the defects that imported conducted apparatus can’t be directly read out conductivity of salt density and the function of the instrument are seldom, so our company develop a suitable instrument -MEWOI-YM-3200. With its easy-manipulation and diverse-function, our product has been unanimously admitted by all customers. |
