Description
1. Product Overview
The GE HYDRAN 201TI is a compact, high-reliability online Dissolved Gas-in-Oil Analysis (DGA) monitor developed by GE Vernova Grid Solutions. Designed specifically for power transformer health monitoring, this intelligent transmitter delivers continuous real-time detection of composite fault gases in transformer oil. It serves as the first-line safety early warning device for power grid transformers and industrial oil-filled power equipment. It effectively identifies potential internal faults such as overheating, discharge and insulation aging. It helps engineering teams detect hidden risks in advance and avoid unplanned power outages and equipment damage.
Traditional transformer maintenance relies heavily on periodic offline oil sampling and laboratory testing. This method has obvious drawbacks. It features long testing cycles, delayed data feedback and inability to capture sudden transient faults. Many potential equipment anomalies cannot be detected in real time between sampling intervals. In addition, manual sampling and laboratory analysis consume large manpower and material resources, raising operational costs. In contrast, the GE HYDRAN 201TI supports 24/7 online uninterrupted monitoring. It adopts high-precision composite gas sensing technology without manual intervention. Each unit passes strict environmental aging testing, precision calibration and long-term operational verification before factory delivery. It has become a mainstream upgrading device for transformer intelligent monitoring systems, old equipment renovation and global industrial e-commerce standardized procurement.
