In the actual process of power supply and use, the magnitude of the current in the circuit is very different. If there is no device to adjust the magnitude of the current, it is likely to cause safety accidents. The current transformer can effectively change the magnitude of the current, so as to protect the electrical equipment and ensure the safety of personnel.

How to reduce the failure rate of outdoor current transformer

When we use the outdoor current transformer, we need to pay attention to reduce its failure rate, but the following two reasons are easy to cause sensor failure.

Harsh working environment of outdoor current transformer.

Outdoor current transformers are generally used in a much harsher environment than indoor ones, so their failure rate is relatively higher. However, due to the uncontrolled nature of the outdoor environment, we need to ensure that the current transformers can be reliably connected when applicable, so as to adapt to the outdoor environment as far as possible.

The technology of outdoor current transformers is not perfect.

Nowadays, outdoor current transformer piles are connected with copper bars. If the contact surface of the connection is not in good contact, the contact resistance is too large, and the contact area is small, the load capacity of the line will be affected, and the transformer will heat up or even burn down.
