RET670 transformer differential protection is one of the important devices used to protect power transformers. Differential protection is based on the comparison of the current difference on both sides of the transformer to achieve, when the transformer internal fault occurs, the differential protection device can quickly detect the current difference and take corresponding protective measures, such as cutting the transformer or starting the fault recorder, to prevent transformer damage and ensure the stable operation of the power system.
RET670 transformer differential protection device is usually composed of current and voltage transformers, differential relays, etc. It can detect the current difference between the two sides of the transformer, and compare and judge according to the set protection threshold. When the detected current difference exceeds the threshold value, the differential protection device will immediately act to cut out the transformer or take other appropriate protective measures.
RET670 transformer differential protection device has the characteristics of high reliability and fast response, which can effectively reduce the influence of transformer failure on the power system and improve the stability and reliability of the power system. At the same time, the differential protection device can also be used in conjunction with other protection devices to form a more complete transformer protection system.
