FUNCTIONAL DESCRIPTION:

DS3800NPOC is a Field Excitation Snubber Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. A field excitation snubber board is an electronic circuit board used in power systems to protect field excitation systems from voltage transients and surges. It is primarily employed in synchronous generators or motors to control the excitation current, ensuring stable operation and preventing damage to the generator or motor. The main purpose of a field excitation snubber board is to provide a path for the dissipation of energy generated during transient events. Transients can occur due to switching operations, lightning strikes, or other disturbances in the power system. When a transient event happens, it can cause voltage spikes or surges that can potentially damage the generator's or motor's field excitation system.

The snubber board typically consists of various components, including resistors, capacitors, and diodes. These components are strategically connected to form a snubber network that can absorb and dissipate the excess energy generated by transients. The board is usually installed near the generator or motor and connected to the field excitation system through appropriate wiring. During a transient event, the snubber board absorbs the excess energy and dissipates it through the resistors and capacitors. The diodes are used to control the direction of the energy flow, ensuring that the excess energy does not propagate back into the generator or motor.

FEATURES:

• Snubber Components: Field excitation snubber boards typically include various components such as resistors, capacitors, and diodes. These components form the snubber network and help dissipate excess energy generated during transient events.

• Voltage Rating: The snubber board will have a specific voltage rating that determines its ability to withstand voltage transients and surges. The voltage rating should be suitable for the application and the voltage levels present in the system.

• Protection Status Indication: Some snubber boards may incorporate status indicators or monitoring features to provide visual or electrical indications of the board's protection status. This can help operators quickly identify any faults or failures in the snubber circuit.

• Customization Options: Depending on the specific requirements of the power system, field excitation snubber boards may offer customization options. This allows the board to be tailored to the unique characteristics of the generator or motor, including voltage levels, system size, and environmental conditions.

FREQUENTLY ASKED QUESTIONS:

What is the primary function of a Field Excitation Snubber Board?

The primary function of a Field Excitation Snubber Board is to suppress voltage spikes and transient overvoltages in the field excitation circuit. These voltage transients are typically caused by the switching of the field excitation power or load, and the snubber board protects the sensitive components from damage.

How does the snubber circuit absorb transient energy?

The snubber circuit typically consists of a resistor and a capacitor connected in series or parallel with the field excitation circuit. When a voltage spike occurs, the capacitor absorbs the excess energy, and the resistor dissipates it as heat. This action limits the voltage rise and smooths out any transients.

What is the typical voltage rating of a Field Excitation Snubber Board?

The voltage rating depends on the application, but typically, the snubber board is rated for voltages in the range of 100V to 1000V for turbine systems.
