Portable Salt Deposit Density Tester for Insulator Contamination Detection

The Insulator Salt Density Measuring Instrument is a professional testing device designed for evaluating insulator surface contamination levels in high-voltage power systems.

It is widely used in power transmission networks, substations, and electrical engineering projects to measure Equivalent Salt Deposit Density (ESDD), conductivity, temperature, and pollution severity levels.

By accurately analyzing contamination conditions, the instrument helps engineers select appropriate insulation structures and creepage distances, effectively reducing the risk of pollution flashover and improving system reliability and safety.

The instrument analyzes insulator surface contamination by measuring equivalent salt deposit density (ESDD) and conductivity of the collected solution.

The system automatically compensates temperature influence and converts conductivity data into standardized parameters such as ESDD, NSDD, and pollution severity classification (SPS).

This enables accurate evaluation of insulation performance and helps determine suitable creepage distance design, effectively reducing the risk of pollution flashover in power systems.
