As transformer operates on the magnetizing phenomenon and it has no rotating parts, its efficiency is very high. In order to determine equivalent impedance, one winding of the transformer is short-circuited. POWER=1.732*VOLTAGE*CURRENT*POWER FACTOR generally as a thumbrule the optimum loading point is STAR-STAR 3 Phase transformer in india and give a better VOLTAGE=11 KV It’s actually not clear to me why Z% it’s expressed in percentage. As these losses depend only on the core size and frequency of the power supply, they stay constant and are independent of transformer’s loading.

Types, Properties, and Application, Type B Miniature Circuit Breaker ( Type B MCB), Gramme Ring and Drum Wound Armature in DC Motors, Three-Phase Transformer – Basics and 2 Connection Methods, Open Delta (V-V) Connection of Transformers, If Z% of the transformer is less, the short circuit current will be more which will produce, On the other hand, it will reduce the voltage drop in the transformer winding. we apply a percentage of rated voltage in transformer primary, current on both windings will also reduce. As transformer losses vary with load, it is often useful to tabulate no-load loss, full-load loss, half-load loss, and so on. Getting the constant losses, point of maximum efficiency can be calculated. Fig2. After such alterations in the transformer, point of ideal operation on percentage loading also get shifted. If the transformer were not operating at full load, the voltage drop would be less. 3.1K views View 1 Upvoter Sponsored by Raging Bull, LLC I’m waiting for more of your content. For achieving better efficiency performance, every manufacturer is supposed to provide the STAR rating sticker on the transformer itself. Curve of efficiency of transformer over percentage loading. Equal percentage impedance is one of the most important criteria for operating transformers in parallel. I only loaded it to 50MVA or 70MVA ? I mean to say that all power sources are rated in KVA. 2500 X 10^3=1.732 X 11 X 10^3 X I Transformers' efficiency tends to improve with increasing transformer capacity. [5] Chart below has been provided by BEE and can be referred as the standard data for the scaling. DC Ammeter : Construction, Working and Temperature Compensation, What is Shunt Capacitor Bank? I=2500KVA/1.732*11KV*0.85 The percentage impedance of a transformer is the volt drop on full load due to the winding resistance and leakage reactance expressed as a percentage of the rated voltage.
