TSC (Thyristor Switched Capacitor)

TSC dynamic reactive power compensation device uses high-power thyristors to form contactless switches, which can quickly switch multi-stage capacitor banks without transition, overcoming the shortcomings of traditional reactive power compensation devices that use mechanical switches for switching, resulting in large impact during the switching process, burnout of switch contacts, and large damage to capacitor. It can achieve capacitor bank switching without impact, inrush current,

TSC (Thyristor Switched Capacitor)
Features

· The controller tracks and measures the power factor of the load in real time, compares it with the preset given value, and dynamically controls the switching of capacitor of different numbers to ensure that the power factor always meets the set requirements. The controller ensures that the thyristor is triggered at zero crossing and dynamically and quickly tracks the load changes.

· TSC can play a good automatic compensation effect on various loads, with fast dynamic response speed (less than 15ms), significant energy saving and consumption reduction effect, and has the functions of reducing losses, stabilizing load voltage, and increasing transformer load capacity. It is an updated product in the field of reactive power compensation.

· The main circuit of the TSC dynamic reactive power compensation device consists of a switch device, a lightning arrester, a current transformer, a capacitor, a discharge coil, a reactor, a valve group, etc.
