Flexible coil large current clamp meter is a loop coil uniformly wound on non-ferromagnetic materials, with no hysteresis effect, almost zero phase error, no magnetic saturation, high linearity and strong anti-interference ability. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current ranges from milliamperes up to ten thousands of amperes. Flexible coil without any exposed metal conductor, non-contact measurement, safe and reliable.
Details of Flexible Coil Clamp Current Meter

The flexible coil does not have any exposed metal conductors, non-contact measurement, safe and reliable. Small in size, light in weight, soft and flexible, it is suitable for narrow environments and dense placement of cables, as well as measuring the current of conductors with large sizes or irregular shapes. No hysteresis effect and strong anti-interference ability. It is especially suitable for current testing in industrial environments with serious signal distortion such as transformer ground cores, thick wires and cables, relay protection, silicon controlled rectifiers, variable frequency speed regulation, semiconductor switches, power electronic conversion equipment, arc welding, etc.

Applications
The Bluetooth version of high and low-voltage clamp ammeter is widely used in substations, power plants, industrial and mining enterprises, as well as testing stations and electrical maintenance departments for current detection and field electrical operations. It can also be used for high and low voltage ratio testing, which measures the high and low voltage currents of the primary and secondary circuits separately, and then calculates the high and low voltage ratio. Insulated rods are lightweight, with characteristics such as moisture resistance, high-temperature resistance, impact resistance, bending resistance, and high insulation.
