        PRODUCTS CENTER


        Three-phase energy meter field calibrator is an advantageous product among electric energy metering series products of the company, and is integrated with energy meter calibrator and low voltage metering device, with energy meter error calibration, error wiring judgment, measurement of transformation ratio, meter reading, harmonic measurement and other functions.

        PEC-HA single-phase energy meter field calibrator is one of Kehui company’s series products. PEC-HA single-phase energy meter field calibrator is a kind of multi-functional modern meter calibration device designed and produced by use of large-scale programmable logic array and a series of advanced technologies and devices, with advanced technology, complete functions, compact structure, reliable performance, convenient use and other advantages. Its successful research and development provides great convenience to field energy meters and various other instruments, and it is a high-end product with excellent performance in single-phase electric energy measurement!

        The multi-functional power consumption tester is a comprehensive detection instrument that integrates various power consumption inspection functions such as the comprehensive error of the metering device, the error measurement of the electric energy meter, and the transformation ratio test of the high and low voltage current transformers below 35KV; it can freeze the power meter It can read events such as power consumption, load curve, loss of voltage and current, programming and cover opening records. It has functions such as analysis of wrong wiring of electric energy meters and calculation of electric quantity recovery. one.

        ● High and low voltage current transformer ratio tester is a new type of electricity inspection equipment for high voltage metering users. It can detect the transformation ratio and polarity of the current transformer used in the metering device at and below 35KV without changing the power supply, so as to effectively prevent the high-voltage metering user from replacing the high-low voltage current transformer or the nameplate of the current transformer and changing the current transformer. The polarity of the secondary line achieves the electricity stealing behavior with less billing; ● It can measure the transformation ratio, polarity and phase-to-phase correspondence of 35KV and below high and low voltage current transformers; ● It can measure the current amplitude of high and low voltage lines up to 35KV; ● Standard 20A clamp, optional 100A, 500A, 1000A clamp or 0-600A flexible clamp meter, with a low-voltage retractable operating insulating rod. ● Large-capacity lithium-ion high-efficiency rechargeable battery, continuous work for 10 hours; ● Closed jaw design greatly improves the accuracy compared with open jaw design ● Long U-shaped jaws, the width of the measured object can reach 50mm; ● Telescopic insulation rod, easy to carry; ● Graphical wide temperature, wide viewing angle liquid crystal, large screen display, which can be seen clearly under low temperature and strong sunlight.

        ● Voltage non-contact, safe and convenient ● Anti-stealing function ● 10kV high voltage CT magnification check ● Do not open the watch cover, do not move the lead seal for inspection ● Check for wrong connection of electric energy meter ● Comprehensive error measurement of metering devices

        This product is developed by our company for the uplink fault diagnosis of the terminal of the low-voltage centralized copying system. It can detect the signal strength of each standard network of the three major operators, and provide the operator and network standard with the best signal to provide judgment for the on-site personnel. in accordance with. This product integrates 3 independent signal detection channels, each channel can diagnose SIM card faults independently or simultaneously, and each channel automatically supports signal detection of the whole network and all standards (supports all standards of mobile, telecom and China Unicom detection). Each channel supports automatic detection of SIM insertion, automatic identification of SIM card information (CCID, IP, operator, network standard, etc.), automatic identification of base station location information (CELL_ID, LAC), uplink PING detection, and uplink master station login detection and other functions.

        ● PT secondary pressure drop wireless test, can measure PT side voltage, instrument side voltage, angle difference, ratio difference, voltage drop, composite error. ● Composed of a handheld host and a handheld extension, it is small in size and light in weight, with short on-site measurement time and fast response. ● Wireless measurement of three-phase PT secondary voltage drop in real time, including PT side voltage, meter side voltage, ratio difference, angle difference, voltage drop,

        YTJD10-XX plug-type three-phase AC voltage sensor is based on capacitive voltage division + isolation structure detection voltage, assembled at the plug position of the European-style plug head of the ring network cabinet, with small size, light weight, high precision, good linearity, easy installation Convenient and other advantages, suitable for measuring three-phase voltage and zero-sequence voltage in ring main unit.

        The EP32I-12T630 deep fusion solid-sealed pole adopts the technology of epoxy resin + encapsulation, and integrates the vacuum interrupter, voltage sensor, current sensor, and energy harvesting capacitor to realize the opening and closing of 10kV high-voltage lines, voltage and current detection, It has the advantages of compact structure, light weight, and maintenance-free, and meets the needs of distribution network automation, miniaturization, and intelligent development.
