Rogowski coil Technology
J&D AC RCT provides non-contact detection of AC current. The AC RCT is clamp type of air-core design with various utility, high reliability & Cost-effective solution for precise current measurements.
The rated current range is 100 to 50000AAC and secondary output value is 0-5/10V or 4-20mADC and 1A/5A/333mVAC/Instantaneous AC voltage.
Rogowski coil is designed as open type and flexible sensor which can be installed to conductor easily. There are two terminals on end of coils and it is designed lead-wire spiral coil from one end to other end which is returned through center of coil.
To provide optimizing transmission, length will be chosen by rated current measuring range. Primary current induced proportional voltage from output of coil. This technology supplies very high sensing on primary current changing value.
Electronic integrated circuit need to be changed from voltage signal to output signal which is proportional versus input current. Rogowski coil is possible to accurate mechanism and linearity sensing by additional electronic component and integrator circuit.
Rogowski coil feature
Rogowski coil has better frequency reaction than normal current transformer due to low inductance and non-magnetic core. It also does not use saturation core, so it is very accurate on high primary current. These kind of sensors are better to apply specially on power measuring system which has high current of fast changing current. To measure high current, normal current transformer is usually big and heavy. In contrast, Rogowski coil is small and light, so it is simply installed as advantage.
Rogowski coil technology
The AC CT has two types of split-core & solid-core design with various utility, high reliability & Cost-effective solution for precise current measurements. The rated current range is 5 to 2400AAC and secondary output value is 0-5/10V or 4-20mADC & 0.1A/1A/5A/333mVAC/Instantaneous AC current.
