As it checks the quality of material used and the procedure of transformer manufacturing hence provide us details of life of transformer, the transformer behaviour on different faults. Transformer Testing Methods Important Transformer Testing Methods. Transformer Testing Basics. Manufacturers test thousands of distribution transformers at worldwide locations each week. In this paper testing of distribution transformer is considered. Table of Contents. Winding Resistance Measurement (Resistance) This transformer testing method is conducted to determine the resistance. PURPOSE: First one is called Separate Source Voltage Withstand Test of transformer, where a single phase power frequency voltage of prescribed level, is applied on transformer winding under test for 60 seconds while the other windings and tank are connected to the earth, and it is observed that whether any failure of insulation occurs or not during the test. Insulation Resistance Test. Transformer Oil Testing. Winding Resistance Measurement is one of the routine tests in a transformer. With our testing system, you can use a single device to determine all of these parameters in an easy way. Different capacity transformers, different measurement methods, different voltage grades, different core structures and so on, their measurement time is different. As power transformer is highly expensive as well as important part of distribution system. These conventional testing methods include measuring a number of parameters, such as the short circuit impedance, transformers ratio, magnetizing current, winding resistance and dynamic winding resistance of the tap changer. Now we will discuss some of the important transformer testing methods briefly. The transformer turns ratio test is used to make sure that the ratio between the … 1. S11 10kv Oil-Immersed Distribution Transformer Scb 10 Rl 10kv Dry-Type Transformer ... Transformer Testing Methods. Before discussing them you should know some basics about testing of transformers. The type and routine test are very important for transformer. Distribution Transformer Testing - Free download as PDF File (.pdf), Text File (.txt) or view presentation slides online. Turns Ratio Testing. Testing of any electrical equipment indicates the extent to which the equipment is able to comply with a customer’s requirements. Two important testing methods of 100 kVA distribution transformer done at manufacturing industries are discussed in this article.
