MGR Technology is renowned name in Thermography for all types of Buildings and Industries including Hotels,Hospitals, Residential, Schools, Manufacturing Industries, Malls, Chemical Plants, Power Plants, FMCG, Moulding, Mines and many more.
At MGR Technology we conduct infrared thermal imaging of machinery and electrical panels, to detect faults before they become major issues. with our worlds best thermal imagers provides accurate real time high resolution images; enabling engineers to detect problems that might otherwise go unnoticed. This gives the opportunity to undertake remedial action prior to costly system failures or production stoppages. Using infrared thermography is effective across all sectors in helping to reduce maintenance costs and even to carry out possible improvements.
Thermal imaging is a process based on processing infrared radiation, that is the heat emitted by objects, into a visible image, making possible to assess temperature distribution on the surface of the observed object without contact.
This is important wherever it is necessary to measure temperature at inaccessible or hazardous locations and also allows for:
In thermographic analysis, contactless measurement in the infrared spectrum is used to determine the temperature of a surface from a distance. Since all objects with a temperature above absolute zero emit thermal radiation of similar characteristics (called black-body radiation), by measuring the radiation and with knowledge of the emissivity coefficient of a given object, its temperature can be determined.
Professional radiometric thermal imaging cameras register temperature separately for each point of the image. For example, in the case of a camera with a 640 x 480 resolution, temperature is registered simultaneously for each of the 307200 points. This makes it possible to conduct detailed analysis of saved thermal images, which display different temperatures as different colors.
All information saved in a thermogram can be used by specialized software delivered with the thermal imaging camera. During analysis of a thermogram, points with maximum or minimum temperature can be determined, the emissivity coefficient of the whole thermogram or a part of it can be corrected, temperature can be read at any point of the thermogram, mean temperature can be calculated, temperature distribution can be presented in the form of histograms or isotherms, the thermal image can be combined with the real image, precisely locate places with a specific temperature, and the color palette can be changed arbitrarily to best represent the temperature distribution. Can provide thermal image overlaps with the real-life image.
Infrared thermometers serves for contactless temperature measurement, and the operate on the basis of analysis of the thermal radiation emitted by the tested object.
An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The test, therefore, determines how effective is the insulation in resisting the flow of electrical current. Such tests are useful for checking the quality of insulation, not only when a product is first manufactured but also over time as the product is used.
Performing such tests at regular time intervals can detect impending insulation failures before they occur and prevent user accidents or costly product repairs.
An insulation resistance test usually has four phases: charge, dwell, measure, and discharge. During the charge phase, the voltage is ramped from zero to the selected/test voltage, which provides
stabilization time and limits the inrush current. Once the voltage reaches the selected value, the voltage can then be allowed to dwell or hold at this voltage before measurements begin.
Once the resistance has been measured for the selected time, the system is discharged back to 0 V during the final phase.
