DGA Test: The Dissolved Gas Analysis test is to identify various gas levels present in the transformer oil. OSR is suitably designed and tested to function at extreme environmental conditions and at intensive seismic levels. This relay can detect only when the oil level is below.
This relay is a security device used in the fields like the transmission of power, as well as distribution. In case of heavy faults due to a surge in oil OSR relay will operate and causes tripping of both HT and LT breakers of the transformer. A machined surface is provided on the relay body for the purpose of testing the mounting of the relay, both in the inclined direction and at right angles to the pipe where it should be horizontal. When the rate of rising pressure oil crosses a certain value then alarm and trip contacts operate. What is OSR Protection or Oil Surge Protection. It's seems like you are on slow network. Rs 4, 300 / Piece (Approx).
B)Model of the auxiliary contact and its fast mechanism. Because the displacement of the moving boundary is much larger than the grid size, to avoid the grid with negative values, or the calculation that does not converge due to excessive grid distortion, the grids with excessive distortion rates or excessive size changes are concentrated together and redivided in the calculation process, to meet the requirements of the distortion rate and size. OSR should be installed between the OLTC diverter champer & OLTC conservator champer. A definite cause of the gas bubbles must be determined and corrected before re-energization of the transformer.

The different transition resistance coefficients are selected, the arcing energy of the main contact, arcing energy of the transition contact, and total arcing energy under various working conditions according to Equation 11 are calculated, and the arcing time is then set as 10 ms. Based on the OLTC simulation model, the oil pressure and oil flow velocity of insulating oil in the oil chamber under different transition resistance values are obtained. Failure of Transformers or its accessories will lead to power outages and repairing of the same will be time consuming and expensive process. 2015) improved the on-load tap changer of the double transition resistance branch triggered by micro-arc and established a new model of active trigger combined with the double transition resistance branch. The Mercury switches are spring mounted within the switch cylinders and protected from possible damage. Actually, the structure of the OLTC is extremely complex, including a large amount of transition area of large space and local irregular small areas. 9 ms. Before adding the arcing energy of the main contact, the oil flow rate near the moving contact and the fast mechanism increases obviously, but the flow in other areas is still gentle and the flow rate is very low.
13 m/s, which is close to the preset 1. Buchholz Relay (Found Only on Transformers with Conservators. Actual prices may vary as per quantity, product dimensions and actual weight sent at the time of shipping. Once every 3 to 5 years, while the transformer is de-energized, functionally test the Buchhholz relay by pumping a small amount of air into the top chamber with a squeeze-bulb hand pump. This work is sponsored by the National Natural Science Foundation of China (No. You seem to be 'Offline'.
