WebFeb 22, 2024 · Short Circuits. When the clamping force exerted on the winding decreases, the strength of the buckling decreases relatively as a result of a decrease in the axial clamping force during a short circuit. Buckling occurred when the initial clamping force was 100% and the residual clamping force was decreased below approximately 30%. WebApr 27, 2024 · Our Transformers Division recently conducted successful Dynamic Short Circuit Test on 1 No. 160 MVA, 220/132/11 KV and 1 No. 60 MVA, 220/33KV transformers. We will be supplying both these transformers to our customer Uttar Pradesh Power Transmission Corporation Ltd. (UPPTCL). Both these transformers were tested at CPRI, …
The test is conducted on the high-voltage (HV) side of the transformer where the low-voltage (LV) side (or the secondary) is short-circuited. A wattmeter is connected to the primary side. An ammeter is connected in series with the primary winding. A voltmeter is optional since the applied voltage is the same as the voltmeter reading. Now with the help of a variac, the applied voltage is slowly increased until the ammeter gives a reading equal to the rated current of the HV side. After reac… Webyour transformers short circuit proof in Test Lab & during service. Dynamic short circuit withstand capability of the windings is analyzed by software, ‘SC 1.47’ based on Electromagnetic field distribution.
