Gas Discharge Tube Arresters (GDT) are used increasingly throughout many industries to protect circuit boards and other components from power system disturbances such as spikes, swells, and other transient overvoltages. GDTs, also known as Surge Protective Devices (SPDs) or Transient Voltage Surge Suppressors (TVSS), are designed to divert or “clamp” a voltage surge to a safe level and ensure that the protected components remain undamaged.

One of the most popular of these types of surge protectors is the type C2520 - 23 CFLF application field. The C2520 - 23 CFLF is designed to provide overvoltage protection for different circuit levels, up to 24kV. It is particularly suitable for installation in medium-voltage rated distribution transformers. The C2520 - 23 CFLF is manufactured in accordance with a range of international standards, including IEC, CSA, GN 81 and UL test procedures.

C2520 - 23 CFLF works on the principle of controlling and limiting the voltage. This is achieved by introducing a controlled amount of capacitance between the protected system and ground. This is known as a capacitance-limiting fuse. This fuse operates in a similar way to an air-gap, but the voltage is clamped from the protected circuit rather than a direct contact with the ground. When a surge occurs, the air gap opens and the energy is dissipated through the activated capacitance-limiting fuse. The device is designed to limit the overvoltage to a safe level, thereby ensuring that the protected circuits remain undamaged.

The C2520 - 23 CFLF surge arrester is designed with four parts: a spark gap, a switch component, a low-noise parallel component, and a surge protection component. The spark gap is a large air gap at the front of the GDT, which limits the amount of electrical energy that can pass through the device. The switch component acts as a switch which will close in the presence of excessive voltage. This switch then diverts the energy away from the protected device, and into the ground. The low-noise parallel component is another switch which is connected in parallel with the spark gap. This component provides additional surge protection by reducing the level of energy that can pass through. Finally, the surge protection component is a device which is designed to protect the circuit from excessive energy.

The C2520 - 23 CFLF works by absorbing and dissipating the incoming voltage to ensure that the protected devices remain undamaged. When the surge arrester is not activated, the electrical energy passes through as normal. However, when a surge occurs, the device begins to operate and the incoming energy is diverted away from the protected device, and towards the ground. The incoming energy is also dissipated as heat, which makes the device highly effective at protecting the protected device from short-term power system disturbances.

To ensure that the C2520 - 23 CFLF remains effective, it is important that the device is regularly tested and maintained. The arrester should be tested on a regular basis to ensure that it is still working to its full capacity. Maintenance should also be carried out as often as possible to ensure that the device remains effective. If the device is not maintained and tested regularly, it may not be able to adequately protect the protected device when a surge occurs.

In conclusion, the C2520 - 23 CFLF is a highly effective GDT which is designed to provide overvoltage protection for different circuit levels, up to 24kV. It works on the principle of controlling and limiting the voltage by introducing a controlled amount of capacitance between the protected system and ground. The device is effective at protecting the protected device from short-term power system disturbances and should be tested and maintained regularly.
