I just made a capacitive coupling clamp with aluminium. When I fed a burst signal of 500V, I could only see 6V across the plates. I have used 1.5mm thickness aluminium sheet. Why its not working as expected?
Nice, an EN 61000-4-4 Burst clamp for IO lines. What is the source impedance of your source? Can you post a schematic?Nikhil N said:
I am first time working in this area, so I didn't understand source impedance of what you are asking. I have a chattering relay circuit, which can produce burst of upto 4KV and I am trying to connect the burst to the capacitive coupling clamp. But I am not seeing the burst coupled with the signals in communication lines.berkeman said:
There could be several reasons why your capacitive coupling clamp is not working as expected. It could be due to incorrect setup or connection, a faulty clamp component, or interference from external sources. It is important to troubleshoot and identify the specific issue in order to determine the solution.
Capacitive coupling is a method of transmitting electrical signals between two conductors without a direct physical connection. It works by creating an electric field between the two conductors, which allows the signal to be transferred through the air. This method is often used in electronic devices to prevent interference and signal loss.
No, not all clamps are suitable for capacitive coupling. You need to use a specific type of clamp that is designed for this purpose, which typically has a high impedance and low capacitance. Using the wrong type of clamp can result in inaccurate readings or signal interference.
To improve the performance of your capacitive coupling clamp, make sure to use a high-quality and properly calibrated clamp. You can also minimize interference by keeping the clamp away from other electronic devices and sources of electromagnetic interference. Additionally, adjusting the sensitivity and gain settings of the clamp can also help improve its performance.
No, capacitive coupling clamps are typically used for high-frequency applications such as testing and measuring electronic devices. They may not be suitable for all types of devices, especially those with low-frequency signals. It is important to consult the manufacturer's instructions and specifications to determine if the clamp is suitable for your specific device.
