GE H201Ci-1 (HYDRAN®201i) Single Channel Dissolved Gas Monitoring Controller
Product Description
H201Ci-1 belongs to GE Vernova HYDRAN 201i family, a single-channel controller designed to work with H201Ti intelligent transmitter to form an on-line dissolved gas monitoring system for oil-filled power equipment. It receives gas data from H201Ti, performs data processing, local LED concentration readout, multi-level alarm, analog output and network communication. Housed in NEMA 4X (IP66) weatherproof enclosure for outdoor installation, equipped with built-in self-diagnostics to detect incipient transformer faults such as partial discharge, overheating and arcing. It supports network architecture, up to 128 H201Ti transmitters can be connected to one controller network. The full set H201Ci-1 + H201Ti is named HYDRAN 201R Model i, widely used for transformer condition assessment and predictive maintenance.
