NRC-XL SERIES 8 SCREW TYPE FLEXIBLE ROGOWSKI COIL

The NRC-XL 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-XL coils have different sizes to cope with different conductors. The new generation of NRC-XL 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-XL series coils have IP68 protection grade, which is extremely suitable for outdoor use.

ME431 MULTI CIRCUIT THREE PHASE MULTI-FUNCTION ELECTRICITY METER

New Products / New Technology

The ME431 Rail-mounted Three-phase Multi-functional Power Meter supports external connection of open-type Rogowski coils or voltage CTs, enabling line-free testing that simplifies procedures and reduces installation costs. It supports up to four three-phase circuits simultaneously, requiring consistent voltage signals while current signals are connected via an RJ45 interface. Compatible with both three-wire and four-wire systems, this meter measures various electrical parameters including current, voltage, power factor, harmonics, power, and energy consumption across A, B, and C phases. Additional versions feature zero-sequence detection and temperature monitoring capabilities.

MI550 HANDHELD THREE PHASE 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.
In addition to the measurement function, Mi550 is equipped with various records, such as waveform records and programmable interval measurement value records. To store and record data, it is internally embedded 32 GB memory card.
With standard configuration of RJ45 Ethernet communication interface, through standard Modbus TCP 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.
