Model IS200EDEXG1B
Category: Deexcitation module
The IS200EDEXG1B model is a deexcitation module primarily used as a bridge and protection board. The main purpose of the board is to store the energy that has been supplied to the generator, and the energy that has been supplied to the generator must be dissipated upon shutdown.
When operating this board, it is important to note that the IS200EDEXG1B board is usually controlled by EXTB. The module provides conductive-sensing feedback and voltage holding to ensure that the board remains operational in the event of a power failure and allows the SCR to deexcite ignition. SCR deexcitation is triggered when the two control inputs read true or when the anode-cathode voltage associated with the SCR exceeds a certain value.
The board is equipped with a Hall effect conduction sensor that senses the magnetic field generated by the magnetic current discharge flowing through the thyristor. The IS200EDEXG1B receives power from the ESPM module. The power supply from the ESPM module should be 24 VDC. The EDEX module then converts the received power to 125 VDC.
What is the shutdown operation on the IS200EDEXG1B board?
There are two shutdown operations on the IS200EDEXG1B board. One is a normal shutdown, i.e. a stop initiated by the operator, where the bridge will be fired at the delay limit, which allows enough time for the field to decay before the field contactor is opened. The second shutdown is the abort stop, and the field contactor in this shutdown will be immediately disconnected.
