Gray Transformer Chemistry Services Direct Evaluation The mechanical properties of insulating paper can be established by direct measurement of its tensile strength or degree of polymerization (DP). These properties are used to evaluate the end of reliable life of paper insulation.
Test Laboratory for Transformer Materials | Transformer ... most important method for the diagnosis of the ageing process as a result of dielectric, thermal, dynamic and chemical ageing in oil and oil-paper insulation is the Dissolved Gas Analysis (DGA). The Siemens Material Testing Laboratory for Transformers offers a comprehensive service, from the collection of samples to analysis and assessment.
Medium-voltage Switchgear｜Medium- & Low-voltage Switchgear ... components, such as current transformers, voltage transformers and multi-function relays are made of the highest quality materials. Heat stress analysis of the switchgear structure has led to a heat-resistant design in which circuit breakers up to 3150 A are self-cooled (i.e. cooling fans not required).

Electrical Distribution - Application Focus Area Damage Consequence of Transformer Oil and SF6 gas leaks. SF6 Gas Leaks. Sulphur hexafluoride (SF6) is a highly potent greenhouse gas used in the power industry for insulation and current interruption in electrical equipment, such as transformers, switchgear busbars and circuit breakers. The gas has a global warming potential of 22,800 times that of carbon dioxide.
Switchgear - Martin Technical The term switchgear, used in association with the electric power system, or grid, refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.

Isolation transformer - Wikipedia isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation; no conductive path is present between source and load.This isolation is used to protect against electric ...
Medium-Voltage Switchgear Doesn't Require SF6 as ... has introduced another medium-voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12.The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas. The switchgear is a new addition to the 8DA and 8DB product family and also works with the proven vacuum switching technology.
