Three Phase Watt Hour Meter Calibrator
RDJL-602 three-phase watt hour meter calibrator is specially designed for on-site inspection of high-voltage power grid metering device operation and fault detection. Due to the use of high-precision internal transformer and clamp type transformer for sampling, the operator can quickly, safely and reliably measure the meter recording error and wiring error. It provides an effective basis for the power system inspectors to check the electricity theft, leakage, find the fault of the metering device, correctly measure and recover the electricity. The calibrator adopts the popular ARM processor, 168m main frequency and 128M memory, and can expand 4G memory card. LCD adopts 7-inch high-definition color touch screen, combined with EMWIN display interface, which makes the instrument interface friendly and easy to operate. Three Phase Watt Hour Meter Calibrator can be operated on full touch screen without keyboard. The instrument supports the seamless connection between the file system and the computer.

The Nonlinear Challenges in Power System Components
In the power supply system, nonlinear issues arise from various elements. For instance, harmonics are generated during the normal operation of generators. Transformers within the grid also contribute to harmonic production. Additionally, DC transmission introduces harmonics, and high-voltage transmission lines can amplify these harmonics. The installation of parallel capacitors in substations is another factor that can lead to the emergence of harmonics. Among these, DC transmission is currently a major source of harmonics in power systems.

What You Don't Know About Power Quality Governance
On the one hand, in addition to the problem of low power factor, a variety of converters and other power electronic devices are increasingly widely used for the introduction of a large number of harmonics into the power grid; on the other hand, a large number of precision instruments are very susceptible to the impact of power harmonics, the power quality of the requirements of more and more high. It is imperative to actively and effectively manage power quality on the user side.
