The Close Interval Potential Survey (CHIP) combined with the Direct Current Voltage Gradient (DCVG) testing technology enables comprehensive detection and evaluation of corrosion and protection of buried pipelines in terms of the effectiveness of cathodic protection systems.
As an effective tool for detecting the cathodic protection level of buried pipelines, the Close Interval Pipe-to-Soil Potential Tester (CHIP) is used to assess the corresponding corrosion risks faced by pipelines. The DCVG investigation is designed to accurately detect, locate, and evaluate the size of coating defects at nearly every location, except when the pipeline is in an area with high contact resistance or an area with significant dynamic stray current interference.
During the use of CIPS and DCVG, it is essential to ensure the periodic synchronous interruption of the output signal of the constant potential instrument. Cái này Bộ ngắt mạch 1003010 sets the on-off cycle in accordance with relevant industry standards. It is fully compatible with CIPS and DCVG circuit breakers available on the market and serves as an ideal alternative to imported circuit breakers.
