Q150 150mm Bus bar and cable ac split core ct current probe clamp

ac split core ct current probe clamp

The model Q150 current probe clamp can be used in large current situation and cooperate to cable fault analysis and cable identification device, used for cable test work. It can even measure up to 3000A AC large current and output 0-5A AC current for other measuring or analyzing system. It can provide 0.5% accuracy class result, ratio 1000/5A, 2000/5A or 3000/5A. Suitable for power plants, factoris and mines to measure power load. The Q150 split core current clamp have large jaw opening designed, high-accuracy, high-sensitivity, versatility, and low phase shift. It is an excellent choice for use in a wide range of power measurement applications including load surveys and demand metering.
