Overview
High precision flexible current transformer range 0A～10000A, coil diameter 12mm, coil inner diameter 200mm-3000mm optional, with integrator easy to integrate into other equipment, such as phase detection analyzer, industrial control device, data logger, oscilloscope, etc.
Non-contact measurement, safe and reliable.
- The flexible coil current transformer consists of a coil and a handle, without any exposed metal conductor in the coil part, non-contact measurement, safe and reliable.
- The flexible current transformer is small, light, flexible, and suitable for narrow environments and densely lined places, as well as for measuring conductor currents of large size or irregular shape.
- Wide measurement range, high accuracy, high reliability, and wide response band. It is especially suitable for relay protection, silicon-controlled rectification, frequency control, semiconductor switching, power electronic conversion equipment, arc welding, and other industrial environments with severe signal distortion.
Application
Flexible current transformers are an indispensable accessory for small, medium, and large electronic companies. The sisco flexible current transformer is suitable for use in power equipment testing, communications and telecommunications, railway and oilfield monitoring, building and construction companies, research and teaching units, industrial and mining records, and other fields.
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: Notes on the use of flexible current transformers current transformers
Generally speaking, the flexible current transformers current transformer is connected in accordance with the minus polarity, so the polarity connection should be correct, once the connection is wrong, resulting in inaccurate measurement, or even a short circuit.
In order to avoid the secondary winding leading to high-voltage electricity into the low-voltage side, the instrument damage, and personal injury, should be set to protect the ground.
For the use of an energy metering transformer, if the secondary circuit is, then no automatic device is required.
