In the power industry, gas monitoring in transformer oil is essential to prevent failures and ensure stable grid operation. Bently Nevada, Inc. has introduced a new online gas monitoring system for transformer oil, the H201CI-1 Hydran 201 series. Designed specifically for the power industry, this advanced monitoring system uses highly sensitive sensors and advanced microprocessor technology to monitor hydrogen, methane, ethane, ethylene, acetylene and other gases in transformer oil in real time.

The core component of the H201CI-1 Hydran 201 series is the single-channel controller, which is used in conjunction with the H201Ti intelligent transmitter to provide display, alarm and analog output. The main terminals of the system facilitate the connection of AC power supplies, alarm contacts, and analog outputs in various configurations. The auxiliary terminal is used to supervise the connection of the H201Ti intelligent transmitter. In addition, the system is equipped with a communication connector for RS-232 to a computer or optional modem, as well as interfaces for RS-485 to other H201Ci controllers.

Notable benefits of the H201CI-1 Hydran 201 series include high-precision measurement, real-time monitoring, fault diagnosis, data storage and remote monitoring capabilities. The modular design of the system also makes installation and maintenance easy and fast. The light-emitting diode digital display installed in the front door can display the gas content in ppm, and is equipped with two gas alarm indicators to ensure that users can timely understand the operating status of the transformer.

The introduction of this online monitoring system for gas in transformer oil marks Bently Nevada’s technological advancement in the field of power system health monitoring, providing an efficient and reliable solution for the power industry. The H201CI-1 Hydran 201 series not only improves the reliability and safety of the power system, but also helps operators to identify and resolve potential problems in a timely manner to ensure the stable operation of the power system.
