Product Description

Product Description

 

YMY-H Equivalent Salt Deposit Density (ESDD) Tester
Overview

This product is a specialized measuring instrument developed for pollution flashover prevention in power systems, designed to measure the Equivalent Salt Deposit Density (hereinafter referred to as "ESDD") on insulator surfaces, as well as solution conductivity and temperature. With its high measurement accuracy, intuitive readings, wide measurement range, and user-friendly operation, the device is widely used in power, education, research, and related industries.

The classification of pollution levels and creation of pollution distribution maps form the foundation of pollution flashover prevention. Accurate pollution distribution maps serve as the basis for determining the creepage distance of electrical porcelain insulation in transmission and transformation equipment. The ESDD value on insulator surfaces provides quantitative data for assessing pollution severity of electrical porcelain insulation, serving as a crucial reference for pollution classification and pollution zone mapping. Therefore, ESDD measurement plays a significant role in ensuring power system safety.

Features

a) Auto-ranging capability;
b) Wide measurement range: ESDD 0.0001mg/cm² to 9.9999mg/cm²;
c) Automatic temperature compensation, directly displaying standard conductivity at 20°C and ESDD;
d) Automatic elimination of cleaning solution's inherent conductivity and original salt content for solutions with conductivity >10μS/cm, reducing cleaning solution requirements;
e) Automatic conversion between non-energized ESDD and energized ESDD via live correction coefficient;
f) Data storage, printing, and upload functions with capacity for 400 datasets;
g) Built-in high-capacity rechargeable lithium battery, suitable for field applications.
