Product details: H201Ti GE HYDRAN 201 series on-line monitoring system for faulty gas in transformer oil
HYDRAN 201 series on-line monitoring system for faulty gas in transformer oil
One: Hydran 201Ti intelligent transmitter
The H201Ti intelligent transmitter has a small cylindrical housing and is connected directly to the dissolved gas monitoring valve of the transformer via a brass adapter.
The H201Ti includes a standard HYDRAN® sensor, thermal conditioning system and microprocessor-based electrical transmitter. Terminals facilitate AC power connections, alarm contacts (high gas, high gas and system failure) and supervisory connections, and an analog 0-1mA non-isolated output. Isolated output 4-20mA is also available. An RS-232 connector for a computer interface is also provided.
Equipped with a thin film keyboard and LCD display, it can be used without an external computer.
2: Hydran 201Ci-1 single-channel controller
The H201Ci-1 control unit is a complete single-channel controller that is used with the H201Ti Intelligent transmitter. Digital/analog boards handle communication transactions and provide display, alarm and analog output functions.
The main terminal is easy to connect: AC power supply; Alarm contacts (high gas, high gas - high and system failure); Non-isolated analog outputs in jumper configurations (0-1mA, 4-20mA, 0-1V, 0-10V) and isolated analog outputs in jumper configurations are available. The auxiliary terminal is used as a supervisory connection to the H201Ti intelligent transmitter. Connectors for communication: RS-232 to computer or optional modem, RS-485 to other H201Ci controllers.
The front door is fitted with a light-emitting diode digital display that displays the gas content in parts per million. There are also two gas alarm lights.
Three: H201Ci-C communication controller
The H201Ci-C control unit is a communication controller. It supervises up to four H201Ti smart transmitters, such as A transformer cabinet (including phase A,B,C, and sometimes an auxiliary), through isolated supervisory connections. The H201Ci-C communication controller has no display screen and does not provide alarm and analog output. It is a specialized interface for the H201Ti intelligent transmitter network to connect to the computer via RS-232 or modem.
