## Long description

The Eti-Polam CTR-30 current transformer is a high-precision device engineered for the accurate measurement and monitoring of electrical currents within industrial power distribution systems. With a transformation ratio of 500/5A and a power rating of 10VA, this component provides reliable signal conversion for secondary measuring instruments. Its design ensures consistent performance in demanding electrical environments, making it a critical element for energy management, load monitoring, and protection relay applications.
Advantages
This current transformer offers exceptional measurement accuracy, adhering to the 0.5 class standard, which ensures that data acquisition remains precise for billing or system analysis purposes. The robust construction of the Eti-Polam CTR-30 allows for seamless integration into existing electrical panels, providing long-term stability and durability. By converting high primary currents into manageable secondary values, it effectively protects sensitive measuring equipment from damage while maintaining high signal integrity throughout the monitoring process.
Suitable for
Industrial power distribution networks
Energy management and monitoring systems
Integration with electrical measuring instruments
Protection relay circuits
Load analysis and power consumption tracking
When it may not be suitable
This device is not intended for use in high-voltage transmission lines exceeding its specified insulation levels. It is also not suitable for applications requiring a transformation ratio other than 500/5A or for environments where the required burden exceeds the 10VA rating.
Key specifications
Transformation ratio: 500/5A
Accuracy class: 0.5
Rated power: 10VA
Application: Industrial electrical systems
How to use
The Eti-Polam CTR-30 should be installed by a qualified electrician in accordance with local electrical safety regulations. The primary conductor must be passed through the aperture of the transformer, ensuring proper orientation as indicated by the device markings. The secondary terminals must be connected to the measuring instrument or protection relay using appropriately sized wiring. Ensure all connections are tightened securely to prevent contact resistance and potential measurement errors.
What to consider before purchase
Verify that the primary current of your circuit matches the 500A rating.
Ensure the secondary device is compatible with a 5A input.
Check that the total burden of the secondary circuit does not exceed 10VA.
Confirm the physical dimensions fit within your existing switchgear or panel layout.
Usage recommendations
Always ensure the secondary circuit of the current transformer is connected to a load or short-circuited before energizing the primary circuit to prevent dangerous voltage build-up.
