General Specifications
This product is available in two types: General-purpose specification type and Electric power specification type.
For the general-purpose specification type, the applicable standard is basically based on Rationalization Level “a” of the Electric Power Cooperative Research Vol. 57, No. 5, “Rationalization of Control and Protection Systems for General Hydroelectric Power Plants.” However, the protection elements comply with the Electric Power Standard B402. The electric power specification type satisfies the conventional Denkyoken (Electric Power Cooperative Research) standard for hydroelectric power.

System configurationMEIDEN

Very compact design system equipped with the necessary functions for hydroelectric power station
Reduction of control cables with the remote I/O function
The subunit equipped with I/O function can be remotely operated from a maximum of 500 m of the length of the optical fiber between the optical FA buses.
The control signal cables can be reduced with optical connection by installing a remote I/O panel equipped with the subunit on the floor of the hydraulic turbine and generator in the power station with a vertical shaft machine.MEIDEN
