Inductrol Voltage Regulator

Voltage ups and downs may be costing you thousands of dollars. Fluctuating voltage is the constant enemy of electrical and electronic equipment. It can reduce operating efficiency, increase maintenance costs, damage expensive electronics and cost you plenty in the process. All electrical equipment is designed to operate at a specific voltage. Unfortunately, input voltage does not always remain constant. While you can operate most electrical equipment over a wide range of input voltage, you do so at the sacrifice of life, economy or optimum performance.

GE INDUCTROL® voltage regulators supply a constant voltage tailored to your equipment. They actually sense inadequate or excessive voltage and quickly make uninterrupted corrections automatically. No need to calculate impedance between source bus and the INDUCTROL — the INDUCTROL maintains the voltage to the load. INDUCTROL voltage regulators are designed to perform either of two basic functions on electric circuits (or a combination of both):

  • Maintain an output voltage or current at ± 1% despite variations in the supply voltage or the connected load.
  • Provide a widely adjustable output voltage or current from an essentially constant supply. The design is simple and reliable. Essentially, the INDUCTROL voltage regulator is a variable ratio autotransformer consisting of laminated steel rotor and stator.

You get outstanding performance

  • Trouble-free operation - because there are no brushes or sliding contacts, very little maintenance is required.
  • Fast, accurate response - with automatic control the INDUCTROL starts correction in 2 cycles and completes within one second for the usual 2% change in line voltage. Unlike step voltage regulators, the dynamic voltage regulation on the INDUCTROL maintains the voltage within ± 1% of the pre-selected value at all times.
  • No waveform distortion – unlike impedance changing regulators, no harmful wave distortion is induced. Problems with sensitive electronic equipment are therefore eliminated.
  • Rugged construction - the INDUCTROL voltage regulator can take up to 100% overload for one hour with ±10% units rated through 225kVA. It has a short circuit capability of 15 times rated current for 2 seconds.
  • High power factor - since it is a variable transformer, the INDUCTROL voltage regulator has almost no effect on the system power factor. This results in a substantial cost reduction.
  • Efficient performance – INDUCTROL voltage regulators are highly efficient. Typical efficiencies exceed 99% at full load and are maintained at relatively high values even at reduced loads.
