Frequently Asked Questions (FAQ):
-
Q: What is the typical application for this 500A/5A current transformer?
A: It is primarily used for accurate energy metering and measurement in low-voltage electrical distribution systems, such as in commercial buildings, industrial plants, and utility substations, to interface with kWh meters, ammeters, and power quality analyzers. -
Q: Can this CT be used for protection purposes as well as metering?
A: While designed for metering accuracy (classes like 0.5, 0.2S), its construction can often support protection functions within its specified limits. For dedicated protection applications (e.g., relay operation during faults), units with different saturation characteristics may be recommended. Please inquire for specific protection-class models. -
Q: Are different ratios or secondary currents available?
A: Yes. As a manufacturer, we offer customization. While 500A/5A is a standard model, other primary current ratings (e.g., 300A, 600A, 800A) and secondary outputs (e.g., 1A) are available upon request to match your system design. -
Q: How do I select the correct rated burden (VA) for my application?
A: The rated burden should be equal to or greater than the total burden of all connected devices (meter, wires). We offer standard burdens of 5, 10, and 15 VA. Providing the specifications of your connected load will allow us to recommend the most suitable option. -
Q: What are the installation requirements for this transformer?
A: Installation is straightforward. Ensure the primary conductor (cable or busbar) passes through the center hole. The secondary terminals must be connected to the measurement device with properly sized wires. The transformer itself should be mounted in a dry, well-ventilated location, and the secondary circuit must never be open-circuited while the primary is energized. -
Q: Do you provide test reports or certificates with the product?
A> Test reports verifying ratio, accuracy, and insulation resistance are available upon request. Our production follows quality management guidelines to ensure consistent performance. -
Q: What is the lead time for standard and customized orders?
A: Standard models typically have shorter lead times. For customized specifications (special ratio, burden, accuracy), the lead time may vary. We provide estimated timelines upon order confirmation to ensure timely project integration. -
Q: From which ports do you ship, and what are the payment terms?
A> We ship from major Chinese ports including Shanghai, Tianjin, Guangzhou, and Ningbo. Standard payment terms like T/T are commonly used, and we can discuss flexible options based on order volume and long-term partnership.
