SR745-W2-P1-G1-HI-A-L-R
The product is named the SR745 – W2 – P1 – G1 – HI – A – L – R module, which is a transformer management relay developed by GE Multilin. It is designed to play a crucial role in power system protection and control, ensuring the safe and stable operation of transformers.
2. Product Description
2.1 General Function
The SR745 – W2 – P1 – G1 – HI – A – L – R module serves as a comprehensive protection and management solution for transformers. It continuously monitors various physical and electrical variables related to the transformer, such as temperature, harmonic levels, and over – excitation. By detecting any abnormal conditions, it can take immediate actions to prevent transformer overloads or damage. For example, if it senses an over – current situation, it can quickly trigger protection mechanisms like circuit – breaker tripping to cut off the power supply, safeguarding the transformer from potential harm. Additionally, it provides necessary protection measures, including over – current protection, over – voltage protection, under – voltage protection, differential protection, and frequency protection. These functions work in unison to ensure the transformer’s safe operation under different operating states and fault conditions.
