Product Features

Motor Control and Protection: The ABB G3HF HENF331051R0009 is designed to perform motor control, primarily through the function. At motor starting, it can limit the inrush current, thereby playing the role of mechanical protection for the motor and electrical protection for the power supply system. In other words, in a direct on line starting application, it ramps the power to the motor, so the inrush current is reduced and does not, in turn, damage the motor windings or trip circuit breakers.

Keeps Your Devices Safe: Armed with overload protection The overload is detected by the device when the current through the motor exceeds the rated value for a predetermined duration. ABB G3HF HENF331051R0009 can then take actions like cutting off the power to the motor, or shutting the motor down, preventing overheating, and potential damage to the motor. This ensures disaster protection for the long term reliability of the motor and the overall system.

Short Circuit Protection: Tracing the electrical circuit and inflated short circuit for 1.5 h. Upon any of the conditions that would lead to a short circuit where the current quickly rises to a high level, the device automatically cuts off power. By responding so quickly, we can save the motor, the device, and other parts of the electrical system from major damage resulting from a high current fault.

Real Time Parameter Monitoring: The ABB G3HF HENF331051R0009 can monitor different electrical parameters like voltage, current, power factor in real time. These monitored values are then displayed on the device interface or can be accessed remotely, if the device is connected to a monitoring system. For instance, operators can use current monitoring to detect abnormal increases, which might indicate a motor problem or a change in the load conditions.

Fault Diagnosis and Alarming: Diagnostic capability has been built in. When the fault, short circuit, or phase failure occurs, the device can identify the fault type and send an alarm. The alarm may be a visual indicator on the device or audible signal, or may be a message to a remote monitoring system. ABB G3HF HENF331051R0009 enables fast identification and resolution of issues, which helps to reduce downtime.

Installation

Pre Installation Checks: To check that the module is compatible with the existing NSD70D teleprotection system configuration. Please check the module for any visible physical damage or defects before installation.

Mounting Orientation: The module must be mounted in the provided slot in the NSD70D chassis and should be seated and secured properly.

Fasten: Choose fittings to stop movement or vibration in operation.

Wiring: Connect the module to the system,according to the system wiring diagram.

Maintain Correct Polarity: Maintain correct polarity to avoid serious damage to the module or system.

Testing: Turn on the system after installation and conduct functional tests to ensure the module works as expected.

Monitoring:  Adjust at the system level and observe the module during initial boot for failure.

Application range

Power transmission systems: ABB G3HF HENF331051R0009 can Enables fast transmission of protection signals to safeguard on high voltage transmission lines.
