Woodward 9905-760 Link Termination Resistor

Woodward 9905-760 Link Termination Resistor 

Functional Description

9905-760 is a Digital Synchronizer and Load Control Module developed by Woodward. It synchronize multiple generators or power sources in a power system. The module ensures that the generators are running at the same frequency and phase angle before they are connected to the power grid or to each other. Digital synchronizers use microprocessors to measure the frequency and phase angle of the generators and provide control signals to adjust their output. It regulates the power output of a generator or power source based on the load demand. It adjusts the output of the generator to maintain a stable voltage and frequency in the power system.

Features

Digital synchronizers and load control modules have several key features that make them essential components in power systems.

Digital Synchronizer

• Measures frequency and phase angle of generators
• Provides control signals to adjust the generator output
• Uses microprocessors for precise synchronization
• Can synchronize multiple generators in parallel operation
• Offers advanced monitoring and protection functions
• Can operate in automatic or manual modes

Load Control Module

• Measures load demand and adjusts generator output
• Maintains stable voltage and frequency in the power system
• Protects generators from overloading and overheating
• Enables efficient power management and load sharing
• Can communicate with other control systems
• Can operate in automatic or manual modes

Cabinet Structural Grounding

• A six-sided metal enclosure is required for the cabinet. Cabinet doors with unshielded windows should be avoided; doors should be as solid metal as possible.
• If a window in the cabinet door is required, it must provide more than 20 dB of RF attenuation from 10 kHz to 1 GHz.
• The enclosure floor and/or top must have cable entry holes; only the floor or top panels may be used.
• The size of the top and bottom cable entry areas must be limited, with the largest dimension of any aperture (hole) not exceeding 152 mm (6 inches). This is especially important when RF transmitters, such as push-to-talk radios or cell phones, are near cable access points.
• When RF transmitters (handheld radios) can be located beneath the plane of the floor in the metal cableway area, floor entry areas must be limited in size, with the largest dimension of any aperture (hole) not exceeding 152 mm (6 inches).
• No floor entry area restrictions are required when RF transmitters (handheld radios) cannot be located below the plane of the floor in the metal cableway area.
• Bonding is required for the cabinet frame and mounting areas (grounded together).
