Insulation testers india – Insulation resistance testers were among the first products offered by Sonel India.
Insulation testers india are performed in order to check the actual condition of insulation of electric systems and appliances.
This is of key importance to the safety of use and to proper functioning of electrical equipment.
Proper condition of insulation is a guarantee of protection against direct touch.
When it comes to testing the condition of insulation, regularity is of key importance.
Such tests are an integral element of control and test works and make it possible to detect any error condition of electrical systems.
During normal operation of electrical systems and appliances, the very impact of those factors lead to aging of insulation.
The five principal factors affecting degradation of electrical systems are: electrical and mechanical damage, aggressive chemicals, thermal exposure, and environmental pollution.
The new stricter safety standards and regulations require changes in the design of testing equipment.
This has resulted in the development of a series of SONEL housings of different shape, ergonomic features, and colors.
However, what is more important is the changes in the design, which resulted in a new, much higher IP rating of the meters and much higher test categories.
Insulation resistance is the total of volume resistance, which depends on the type of the insulation material, and surface resistance, which depends on the cleanliness of the surface.
Its value depends on a number of factors, to include temperature and voltage.
The factors that have the greatest impact on the process of measuring the parameters that characterize insulation resistance are: humidity, temperature, test voltage, test time, and cleanliness of the surface of the insulating material.
The insulation leak current is a small resistance current which has to components
