INFORMATION

Description

Measurement with three current transformers guarantees an analogue reading of the company meter. The Computer SMART III Fast reactive energy regulator is the only regulator on the market that offers the possibility of using 3 measurement transformers in addition to the conventional method of measuring with a single current transformer, as well as providing the functions of an integral power analyzer and controlling residual leakage currents.
Computer SMART III Fast is a regulator that ensures excellent preventive maintenance by means of programming its alarms and the options for testing the capacitor status, offering maximum supervision and safety of your compensation unit.

Applications

Computer Smart III fast it’s the ideal solution to compensate installations with a variation of quick load, between 40 ms and 4 seconds, and/or large unbalances between phases, such as welding units, cranes, lifts and lifting units, smelters, hospitals, automotive industry or any other sector or unit that requires an efficient compensation of the power factor.
The connection of 1 or 3 transformers makes computer SMART III Fast the perfect regulator in any installation, allowing the following:

  • Changing from 1 to 3 transformers in the following cases:
    • Single-phase fast changing equipment
    • Example: Single-phase welding
    • Replacing the regulator of any capacitor bank
  • Perfect for installations with up to 4 objective cos φ, since it can adapt to any compensation need (different time periods).
