Heat run test is an essential test for the continuous satisfactory performance of the Electrical equipments.
If the equipment is having any hidden quality problems the test reveals the defect by abnormal temperature rise. Most of the Electrical equipments and components undergo Temperature rise test specified by the Electrical standards and specifications.
In a laboratory or an industry injecting rated current to the equipment is always a challenge. Measurement of temperature rise is to be very accurate and appropriate measuring instruments should be also available.
The limitation of conducting the test, therefore, rests on the availability of source voltage and power to drive the required current. It is not feasible to conduct the test if adequate source is not available with testing Agency. |
