FAQs

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: Current transformer wiring principles

Do not allow open circuits. A secondary open circuit is easy to cause safety accidents because the secondary open circuit will lead to core overheating and induction of high voltage.
There must be a point of grounding. A current transformer is a measurement for high voltage, if there is a point of grounding, you can introduce high voltage to the earth, but note that grounding can not be two points, so as not to shunt.
Protection level and measurement level can not be connected to the wrong. Once the two are connected wrong, then it may lead to relay protection is not responsive and inaccurate power measurement.
Unused windings need to be shorted to avoid affecting the measurement accuracy, but the current transformer has multiple taps, the unused taps that need to be carried out and can not be shorted.
