ROGOWSKI COIL CURRENT SENSOR

NRC screw type flexible Rogowski coil
The NRC series is a new generation of flexible Rogowski coil (Rogowski® coil) current sensors, which are especially suitable for measuring in combination with portable devices. NRC coils have different sizes to cope with different conductors. The new generation of NRC coil strengthens the shielding layer and greatly reduces the influence of external magnetic fields; it can be directly connected to our rail-mounted and panel-type meters without the need for external integrators. NRC series coils have IP68 protection grade, which is extremely suitable for outdoor use.
High quality with below features:
Excellent linearity
Wide dynamic range
Not damaged by large overloads
Excellent degree of rejection to the external current conductor
No danger from open-circuited secondary
Zero power consumption
Small position error
Soft and light, easy to install
Long-term stability
Wide dynamic range
IP68 protection level
UL certification (Optional)

HANDHELD POWER QUALITY ANALYZER

New Products / New Technology

Mi550 handheld three phase power quality analyzer, externally connected with open type Rogowski coil or voltage type CT, it can realize none dismantling wire test, simplify test steps, save construction cost, and is more convenient for engineering test as well as the inspection and maintenance of distribution system.
Support systems of single-phase and three-phase. It can measure multiple electrical parameters such as current, voltage, power factor, power, energy, and power quality parameters including harmonic, unbalance degree, voltage swell and voltage dip, etc.
Mi550 is equipped with various records, such as waveform records and programmable interval measurement value records. Internally embedded 32 GB memory card to store and record data. With RJ45 Ethernet interface, Modbus TCP communication protocol, it is compatible with various configuration systems and could transmit the electrical parameters collected by the front end to the system data center in real time.
