Transformers are vital components of the electric power system used to deliver electric power from one utility or industrial source to another. A fault within the transformer itself can result in significant physical damage to the transformer, costly downtime, and can even pose a risk to personnel. To protect transformers from these failures, the oil surge relay is engineered to detect rapid movement of the transformer oil caused by internal faults, such as short-circuits or insulation failures. For power systems that are becoming more and more necessary to provide reliable and efficient electricity to customers, it is critical to have a high quality oil surge relay installed so that a transformer can perform at optimum levels and continue to provide an acceptable level of safety to both workers near the transformer and the utilities and industries they serve. This guide will give you the information you need to be knowledgeable about the oil surge relay, how it works, its functionality, its applications, and its product options to help you select the best product for a specific application. What is The Oil Surge Relay? An oil surge relay is a protective device that detects rapid flows of transformer oil as a result of internal short-circuits, insulation failures and winding faults. Oil surge relays are usually mounted between the transformer tank and its conservator (gas tank for the transformer), typically in switching compartments where OLTC are installed. There is an abrupt change in oil flow when there is a fault. The oil surge relay detects this unusual condition and immediately activates an alarm or tripping contacts, which isolates the transformer to minimize the risk of additional damages. Due to its rapid response time, the oil surge relay is very effective at preventing catastrophic transformer failures. Importance of Oil Surge Relay in Transformers The Oil Surge Relay is an important component of transformer protection systems. Transformers operate under electrical tremendous stress and can quickly develop more severe problems if they have not been detected shortly after the fault occurs. Three ways that Oil Surge Relay provides key importance to transformer protection systems include: 1. Detects sudden internal faults immediately 2. Protects OLTC compartments from destruction 3. Prevents transformer failure 4. Provides increased safety during transformer operation 5. Decreases costs for maintaining and repairing transformers By using a reliable oil surge relay, you can expect your transformer system to provide long-term reliability and performance. The oil surge relay works by measuring the velocity and pressure of oil exiting the transformer from the tank. Oil flows through a transformer at a constant rate under normal circumstances. When there is an internal fault in a transformer, a sudden movement of oil occurs. The mechanical sensing element in the Oil Surge Relay can detect the change in the movement of oil. It causes the relay to activate alarm or trip contacts Therefore disconnecting the transformer to prevent further damage. The Oil Surge Relay is a very reliable means of quickly detecting an internal fault in a transformer. Functions of the Oil Surge Relay The Oil Surge Relay has several important functions: Fault Detection The Oil Surge Relay detects internal faults by measuring the abnormal flow of oil through the relay. Instant Protection The Oil Surge Relay provides almost instant activation of an alarm or trip contacts, which significantly reduces the potential for catastrophic damage. OLTC Safety The Oil Surge Relay provides protection to on-load tap changers, which are extremely sensitive components. System Protection By isolating the faulted transformer(s), the Oil Surge Relay also protects the entire electrical system. Oil Surge Relay Applications The Oil Surge Relay is commonly used in industrial applications where there are transformers: Power Generation Plants Electrical Substations Industrial Manufacturing Renewable Energy Systems Large Commercial Facilities The Oil Surge Relay provides uninterrupted and safe transformer operation for many of these applications.
