CTK Type Square Zero-sequence Current Transformer

Recommendation for popular purchases: Welcome (Wenzhou) Electric Co., Ltd. CTK series zero sequence current transformers

Working principle

In the operation of our power system, once zero sequence grounding current occurs, Comewill factory's high quality CTK Type Square Zero-sequence Current Transformer can seamlessly cooperate with relay protection devices and signal systems, stably trigger the action of device components, and implement the functions of protection and monitoring. Its feature of not selecting equipment and stable linkage allows buyers to avoid worrying about adaptation issues, which is also one of the key reasons why it has become popular in procurement.

If an electric shock accident or leakage fault occurs in the circuit, the secondary side of the transformer will immediately respond and output zero sequence current. At this point, the devices connected to the secondary line will promptly activate the protection mechanism - either automatically cutting off the power to prevent the fault from expanding; Either immediately issue an alarm signal to remind the staff to handle it in a timely manner, minimize the safety risks of the electrical system, and also protect the personal safety of on-site personnel.

Why choose us?

For procurement projects with electrical safety protection requirements, this CTK Type Square Zero-sequence Current Transformer is reliable, durable, and has direct protection effects, making it a high-quality procurement choice to enhance the safety level of the entire power system. If you need bulk procurement or have customized parameters or technical consulting needs, Welcome (Wenzhou) Electric Co., Ltd. can provide professional one-stop services. Whether it is procurement process docking or subsequent technical support, we can help you solve it properly and fully meet the procurement needs of different fields.

CTKs (Current Transformers): Core Advantages

CTKs are solid, reliable devices built for three-phase electrical systems—here’s what makes them stand out in real-world use:

Catches unbalanced current and ground faults: CTK Type Square Zero-sequence Current Transformer are made to measure unbalanced current in three-phase setups (that’s the total of the three phase currents). This means they can spot ground faults, which happen when fault current leaks from one or more phase conductors to the ground.
Super sensitive: Even tiny amounts of ground fault current don’t slip past them. That’s a big deal for protecting equipment from damage and keeping workers safe from electric shock. Consistently accurate: They deliver precise readings of the current’s zero-sequence component, even when there’s a lot of electrical noise or interference messing with the system.
Easy, non-intrusive installation: You just mount them around the neutral conductor of a three-phase system—no need to break the circuit or shut down power to the load. Setup is straightforward and doesn’t disrupt operations.
Works across different frequencies: Designed to operate from 50Hz to 400Hz (the common range for most applications), CTK Type Square Zero-sequence Current Transformer are flexible enough to fit a variety of electrical setups.
Low burden on the system: They don’t put extra strain on the circuit, and they won’t throw off the accuracy of other measurement devices in the system.
All in all, CTK Type Square Zero-sequence Current Transformers are dependable, accurate tools that play a key role in protecting electrical systems from ground faults. They keep both people and equipment safe, making them a go-to choice for industrial and commercial electrical protection needs.
