Specialising in degree of polymerisation (DP) analysis of paper insulation retrieved from high voltage apparatus.
Degree of Polymerisation is an integral part of the End of Life evaluation process.
To provide detailed analysis of the ageing characteristics of High Voltage apparatus paper insulation.
Polaris Diagnostics & Engineering Ltd operates a state of the art laboratory specialising in, and dedicated to carrying out Degree of Polymerisation (DP) analysis of paper insulation retrieved from transformers and other items of high voltage apparatus. The laboratory has been operational since March 2018 is fully ISO accredited for Quality, Environmental and Health & Safety, with analysis being carried out in accordance with IEC 60450:2004/AMD1:2007. This facility is unique to Scotland, offering services to our UK clients and is open to receiving international commissions from around the world.
Degree of Polymerisation Analysis
Applications of DP Analysis:
- To Establish The Insulation Ageing Characteristics Of The High Voltage Apparatus
- To Determine The Relative Ageing Of Adjacent Layers Of Insulation
