Q1: What is a flexible current transformer?
A1: A flexible current transformer is an AC current sensor consisting of a toroidal coil uniformly wound on a non-ferromagnetic material and an integrator. The output signal is the differentiation of current against time and can be directly applied to the conductor being measured to measure AC current.
Q2: What are the advantages of flexible current transformers?
A2: Flexible current transformers are essentially just a pair of cables, allowing you to easily reach even the tightest sections. This feature is also particularly handy when you are working in high places. The design of the flexible current transformer eliminates the risk of encountering a secondary open circuit. As a result, the risk of electrocution or transformer overload is mitigated. Of course, this doesn't mean you can be lax about safety procedures, but it does provide a sense of security when working.
Q3: What are the wiring methods of current transformers?
A3: There are two types of current transformer wiring, the first is the use of two current transformers two-phase V-shaped wiring and two-phase current differential wiring, and the second is the use of three current transformers three-phase Y-shaped wiring, three-phase triangle wiring, and zero sequence wiring.
Tips: What are the advantages of sisco current transformers compared to conventional ones?
Better accessibility
Traditional current transformers are by nature bulky, which can pose a problem when you have to tap into circuits in tight spaces. Flexible current transformers, on the other hand, are essentially just a pair of cables, allowing you to easily reach even the tightest sections. This feature is also particularly handy when you're working in high places.
Better safety
The design of flexible current transformers eliminates the risk of encountering secondary open circuits. As a result, the risk of electric shock or transformer overload is mitigated. Of course, this doesn't mean you can be lax about safety procedures, but it does provide a sense of security when working.
Overall, flexible current transformers offer a wealth of benefits but facilitate an easier transition with the same features as traditional current transformers. New isn't always better, but in the case of flexible current transformers, they are definitely worth the transition.
