Corrosive Sulphur | CS100 | Corrosive Sulphur Kit
The CS100 Corrosive Sulphur Kit is a real alternative to expensive laboratory tests for the determination of corrosive copper sulphide deposits. Such deposits repeatedly lead to a number of errors and thus to transformer failures. In most cases, copper sulfide deposits cannot be detected during normal inspections. The copper wire would have to be unwound and the paper de-oiled to see the shiny deposits. The copper wire is usually dark or multicolored and the discoloration can significantly vary over the entire length of a conductor. Until now, the only way to detect corrosive sulfur in the oil was by expensive laboratory tests.
Sulfur can occur in transformer oil in various forms and compounds. Copper sulfides can appear in very different looks.
This makes it extremely credible that countless malfunctions in transformers and reactors are due to undetected copper sulfides. The portable CS100 Corrosive Sulphur Kit enables a fast and cost-effective test. Copper Corrosion Tests – Comparison Tables (Procedure based on ASTM D1275 Method B
IEC 62535 – usually the so-called CCD test. – Test method: accelerated oxidation at high temperature on copper conductors wound in kraft paper, visual assessment (former Cigre A2.32.TF01 method) Purpose: to determine the presence of corrosive sulphur compounds that could contaminate the cellulose of conductors with copper sulphide.
ASTM D1275, Procedure B – Test Method: Accelerated High Temperature Oxidation on Electrolytic Copper Strip, Visual Assessment 48 hours at 150°C (Procedure A: 19 hours at 140°C) Purpose: To determine the presence of corrosive sulfur compounds that could contaminate copper surfaces.
