Transformer Testing software is a solution for testing of new as well as repaired  transformers. It uses an interface to WT series power analyzer for online display of electrical parameters and capturing required readings. Winding resistance of HV side and LV side are measured and fed in software along with Insulation resistance values.
No Load test is conducted on transformer, In Open circuit test / No Load Test the voltage at rated frequency is applied to that LV side with the help of a variac of variable ratio auto transformer and data is captured automatically via power analyzer. The HV side of the transformer is kept open.
In Short Circuit Test / Load Loss Test A low voltage of around 5-10% is appliedvto that HV side with the help of a variac (i.e. a variable ratio auto transformer )vand the LV side of the transformer is short circuited. Electrical parameters arevonline displayed on screen, with the help of variac applied voltage is slowly increased until the current reading reaches equal to the rated current of the HV side. Data is captured directly via power analyzer.
The software calculates the load loss and impedance voltage (%) and declares the transformer as PASS / FAIL as per predefined criteria.The test data is stored and can be retrieved easily in future when needed. Reports can be stored at web server for worldwide access.
