Description
1. Product Overview
The GE H201Ci-1 is a high-precision single-channel intelligent controller belonging to the GE HYDRAN series transformer oil gas monitoring system. It serves as the core data display and signal processing unit for matching HYDRAN 201Ti intelligent transmitters. This device is specially developed for online monitoring of power transformer internal faults. It focuses on real-time collection, analysis, display and remote transmission of dissolved hydrogen gas in transformer oil. It provides accurate and reliable data support for judging transformer operating status and early fault warning.
Power transformers are core equipment of power grid operation. Internal overheating, insulation aging and partial discharge will produce hydrogen gas, which is the key characteristic gas of potential transformer faults. Traditional manual periodic sampling and detection methods have obvious limitations. They feature long detection cycles, slow data update and delayed fault response. They cannot realize 24-hour real-time state perception. Ordinary generic monitoring controllers have poor matching performance with professional gas sensors. They suffer from low measurement accuracy, single signal output and unstable long-term operation. In contrast, the GE H201Ci-1 adopts professional oil gas monitoring algorithm and industrial-grade hardware design. It perfectly matches GE supporting transmitters. It integrates real-time data display, multi-level alarm output and diversified communication transmission functions. Each device passes strict precision calibration and industrial environment testing before delivery. It acts as a standard original spare part for power transformer monitoring system construction and upgrading, and fully supports standardized global industrial e-commerce procurement.
2. Core Product Features & Competitive Advantages
Power grid transformer monitoring scenarios require monitoring equipment with high precision, high real-time performance and strong stability. Ordinary monitoring controllers are prone to data drift, insensitive response and single function in long-term outdoor and substation industrial environments. These defects lead to missed judgment and misjudgment of potential transformer faults. To solve common industry pain points, the GE H201Ci-1 realizes comprehensive upgrades in detection accuracy, functional diversity and industrial environmental adaptability.
