## Long description

The FF TI-250/5 Current Transformer is a precision-engineered device designed to facilitate accurate electrical measurements and monitoring within power distribution systems. With a rated power of 5VA and an accuracy class of 0.5, this transformer provides reliable signal conversion, making it an essential component for energy meters and protection relays in both industrial and commercial settings. Its robust construction ensures consistent performance even in demanding electrical environments.
Advantages
This current transformer offers high measurement precision, ensuring that connected monitoring equipment receives accurate data for energy management and system protection. The device is built for durability and stability, maintaining its performance characteristics over long periods of operation. Its compact design allows for efficient installation in standard electrical cabinets, while the standardized output ensures compatibility with a wide range of measuring instruments and relay systems.
Suitable for
Industrial power distribution monitoring
Commercial energy metering systems
Integration with protection relays
Electrical load analysis and management
This device may not be suitable for applications requiring extremely high accuracy classes beyond 0.5, such as specialized laboratory testing or high-precision billing meters that demand class 0.2 or higher. It is also not intended for use in high-voltage transmission lines or environments where the primary current significantly exceeds the rated capacity of the transformer.
Key specifications
Rated power: 5VA
Accuracy class: 0.5
Primary current: 250A
Secondary current: 5A
Application: Indoor electrical distribution
To use the FF TI-250/5, the primary conductor must be passed through the aperture of the transformer. The secondary terminals should then be connected to the measuring device or relay using appropriate gauge wiring, ensuring that the polarity is observed correctly to prevent measurement errors. All connections must be tightened securely to maintain low contact resistance and ensure the safety of the installation.
What to consider before purchase
Verify that the primary current matches your system requirements
Ensure the secondary current is compatible with your energy meter or relay
Check available space in the electrical panel for mounting
Confirm that the accuracy class meets your specific monitoring needs
Usage recommendations: Always ensure that the secondary circuit of the current transformer is never left open while the primary circuit is energized, as this can lead to dangerous high-voltage spikes and potential damage to the device. Installation should be performed by a qualified electrician in accordance with local electrical codes.
