1. What current ratios are available for the LMZ-165 current transformer?
The LMZ-165 current transformer is available with a wide range of primary current ratios, from 50/5A up to 6000/5A. Different ratios can be selected according to the rated current of the busbar or electrical system.
2. What size busbar or cable can fit through the LMZ-165 current transformer?
The LMZ-165 features a large 165 mm window, making it suitable for large busbars, multiple cables, and high-current electrical installations. Customers should provide the busbar or cable dimensions before ordering so the installation clearance can be confirmed.
3. What is the rating factor of the LMZ-165 current transformer?
The rating factor depends on the selected current ratio and ambient temperature. The LMZ-165 supports extended current operation, with different rating factors specified at 30°C and 55°C. Please provide your required current ratio and maximum operating current for selection.
4. Can the LMZ-165 be used for both metering and protection applications?
Yes. The LMZ-165 current transformer can be configured for metering or relay protection applications depending on the required accuracy class, burden, and system specification. Please provide the application details when requesting a quotation.
5. Does the LMZ-165 current transformer comply with IEEE C57.13?
Yes. The LMZ-165 is designed according to IEEE C57.13 requirements, making it suitable for electrical distribution, metering, switchgear, and industrial power monitoring projects that require IEEE-standard current transformers.
