Voltage Regulating Transformers
The Jindal's Linear Voltage Regulating Transformer has been designed to meet a wide range of heavy-duty industrial applications as well as for Electricity Supply Utilities. Globally, these have become an established method of control, wherever continuously variable on-load control of voltage and power is needed. These can also be used to control many industrial processes like adjusting temperature, flow speeds, drive speeds, etc. To a pre-set programme.
Jindal's voltage regulating transformers and regulating units combine fixed ratio transformers with regulating transformers to extend their rating, versatility and applications. Depending on cooling medium and connection, designs range from low order KVA's to several hundered KVA as a stand alone unit. Using multiple voltage regulators, in combination with fixed ratio transformers, capacity levels are extended in to the 5 MVA range.
The applications for Jindal's voltage regulating transformers and units fall in to two broad basic groups:
Maintaining constant output levels by compensating automatically for variations in supply voltage. Our voltage controllers fall in this category, which are installed either along with the main distribution transformer/panel to stabilize the voltage to entire plant, or to individual machines or processes to hold voltage/current/power/temperature/lighting intensity constant. They are equally suited to A.C. Or D.C applications.
Giving a smoothly variable output voltage for different and continuous heavy-duty industrial processes, wherever voltage has to be smoothly adjusted on load over a wide range of control with out effecting the power factor or waveform of the system. Our silicon power rectifiers and A.C. Variable voltage transformers fall in this category.
Manual/Mechanical control: For the simplest requirement, a 'T' handle or hand-wheel is provided at a convenient operating height.
Motor control: With the help of push-button controls through a single phase reversible motor, driving through an internal gear box.
Automatic control: With help of a voltage sensing relay in case of a voltage stabilizer, and with help of single isolators to facilitate PLC compatibility/automation for rectifiers and variable voltage transformers.
