Welcome to Jindal Electricals

Voltage fluctuation is a common phenomenon in every part of the country. The industrial units, which are running 24 hours, face the problem of low and high voltage. 90% of industrial load is of motors.

Electric motors draw considerably high current at low and high voltage. This higher current affects the electrical motors (particularly smaller motors upto 7.5 H.P.) in three ways.

  1. Higher current produces higher losses in electrical motors which causes premature failure of winding. 

  2. These higher losses of electric motors also increase the losses of cables, switches, transformers and other associated equipment.

  3. For smooth continuous operation of motors, over load relays are usually set at 20% higher setting. If single phasing occurs..

 INNER VIEW OF STABILIZER

With the installation of the stabilizer and maintaining 390/400 volts, the motor will run smoothly drawing 15-20% lesser current and correspondingly the relay settings can be reduced by 15-20%. In case single phasing occurs, the relay will trip in 40-50 seconds. The motor can withstand the high current for this period and will be safe. Also, the relays, contactors, switchgears, etc. incorporated with the motor will be safe. 

WHO NEEDS A STABILIZER

The industries which are having acute failure rate of lighting equipments such as bulbs, chokes, motors (particularly smaller rating motors upto 7.5 H.P.), contactor coils, etc. definitely require a stabilizer.

HOW TO ACCESS HIGHER LOSSES & LOW POWER FACTOR IN INDUSTRIAL UNITS WITHOUT INSTALLING STABILIZER

  1. Note down hourly readings of current and voltage of one motor running at constant load for 2-3 days. From the different readings, you will observe that the current drawn by the motors in minimum at 390/400 volts, as compare to the current drawn at other voltages. This means that power consumed by the motor is minimum at 390/400 volts.

  2. Also note down hourly readings of voltage and power factor from your main panel for 2-3 days. From the readings you will observe that power factor is maximum at 390/400 volts inmost of the readings in comparison to the higher voltage readings.

INNER VIEW OF REGULATOR

If you find that the above factors are true then you will have following advantages after the installation of stabilizer.

ADVANTAGES

  1. REDUCTION IN BREAKDOWN OF ELECTRICAL EQUIPMENTS

  2. REDUCTION IN POWER CONSUMPTION

  3. IMPROVEMENT IN POWER FACTOR

  4. REDUCTION IN MDI

CARBON ROLLER ASSEMBLY

PAYBACK PERIOD

Owing to its high efficiency and associated benefits, the payback period of Jindal's Servo Voltage Stabilizer is within 6-12 months and depends upon the input variation and the number of working hours.

DESCRIPTION OF JINDAL'S MAKE AUTOMATIC VOLTAGE CONTROLLER

Jindal's Automatic Servo Voltage Stabilizer primarily consists of the following 

  1. Linear type continuously variable voltage regulator.

  2. Double wound buckboost transformer.

  3. Electronic control circuit and meter panel.

The regulator and buckboost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators, if necessary are provided for effective cooling. Their core is built from grain oriented silicon steel Laminations which keep losses to the minimum and they are wound with electrolyitic grade copper to minimise the losses, vacuum impregnated and over dried as per IS.
