Three-Phase Capacitance and Inductance Tester Manufacturer Product Overview:
Power quality issues are mainly caused by the terminal load side. Among them, impact reactive loads can cause severe voltage fluctuations in the power grid, reduce power supply quality, and result in low power factor operation of the grid. With the development of power electronics technology, it not only brings energy saving and positive aspects of energy conversion to modern industry, but also the widespread application of power electronic devices in various industries has brought new and more serious damage to power quality, becoming the main source of harmonic pollution in the power grid. Power departments are paying more and more attention to power quality issues, and reactive power compensation complete sets of devices have been widely put into distribution network operation. Among them, power capacitors are important equipment for the stable operation of the power system. Reactive power compensation devices should meet the requirements of automatic tracking and real-time compensation, which inevitably requires frequent switching of compensation capacitor banks. This will produce overcurrent and overvoltage impacts. After long-term operation, it may cause insufficient capacitance or even damage to the capacitors, affecting the stable operation of the power grid. In order to avoid this situation, detect capacitor defects early, ensure reliable operation of equipment, and avoid fault expansion, it is necessary to regularly test capacitor banks. On site, capacitors are usually connected in parallel in groups. The traditional method is to remove the capacitor busbar and then use a traditional capacitance meter for measurement. The workload of disconnecting wires to measure capacitance is very heavy, and frequent disconnection can cause screws to slip or not be tightened, leaving safety hazards and easily causing secondary damage to the capacitors.
In view of the actual situation on site, Yangzhou Tuopu Electrical Technology Co., Ltd. has timely developed the TPCLC-S+
Automatic Three-Phase Capacitance and Inductance Tester using a new testing method. This instrument internally synthesizes a three-phase AC test source, and can directly measure the single-phase capacitance of parallel capacitor banks or three-phase capacitors of various connection types without disconnecting wires. It can also measure the inductance of various reactors. The wiring is simple, and testing and recording are convenient, improving work efficiency. It uses a large-screen color LCD as the display window, with menu operation and Chinese prompts, integrating multiple parameters on one screen. The human-machine interface is friendly, and it is easy and quick to use, making it a professional product for power users at all levels.
