Motor Control Center (MCC) Panel : A M otor Control Center ( MCC ) is an assembly of one or more enclosed sections having a common power bus and principally containing motor control units. Motor control centers are in modern practice a factory assembly of several motor starters. A motor control center can include variable frequency drives, programmable controllers, and metering and may also be the electrical service entrance for the building. Range of Voltages : Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contractors for switching and with separate compartments for power switching and control. Uses : Motor control centers have been used since 1950 by the automobile manufacturing industry which used large numbers of electric motors. Today they are used in many industrial and commercial applications. Where very dusty or corrosive processes are used, the motor control center may be installed in a separate air-conditioned room, but often an MCC will be on the factory floor adjacent to the machinery controlled. Components of MCC : A motor control center consists of one or more vertical metal cabinet sections with power bus and provision for plug-in mounting of individual motor controllers. Very large controllers may be bolted in place but smaller controllers can be unplugged from the cabinet for testing or maintenance. Each motor controller contains a contractor or a solid-state motor controller, overload relays to protect the motor, fuses or a circuit breaker to provide short-circuit protection, and a disconnecting switch to isolate the motor circuit. Three-phase power enters each controller through separable connectors. The motor is wired to terminals in the controller. Motor control centers provide wire ways for field control and power cables. Specifications : Each motor controller in an MCC can be specified with a range of options such as separate control transformers, pilot lamps, control switches, extra control terminal blocks, various types of thermal or solid-state overload protection relays, or various classes of power fuses or types of circuit breakers. A motor control center can either be supplied ready for the customer to connect all field wiring, or can be an engineered assembly with internal control and interlocking wiring to a central control terminal panel board or programmable controller. We Arzoo Energy are the Well-Known Manufacturer of the Efficient and Reliable Motor Control Center (MCC) Panel with the team of highly skilled and Experienced Engineers,as always want to serve the society by making new innovations in the field of Electrical Product Manufacturing.

VOLTAGE VARIATION: Voltage variation is a common phenomenon all over the country. Generally voltage is low during daytime and high during the night hours. Moreover on holidays, peak hours, rainy days and when the agricultural load is switched off, the voltage rises quite sharply - which is more dangerous. Electrical equipments are designed for 230 Volts (single phase) or 400 Volts (3-phase) and operate with optimum efficiency at its rated voltage. 90% of industrial load consists of motors. Electric Motors draw considerably high current at HIGH voltage and increase energy consumption, increase MDI and reduce power factor etc. These excessive power losses of motors generated at higher voltage results in their premature failure. Similar is the case with Bulbs and Tubes, when voltage increases above 230 Volts. For example, at 270 Volts, the power consumption of 60W-bulb increases almost 40% and the life of bulb reduce from normal 1000 Hours to mere 100 Hours only (as per analysis report of ISI mark bulb manufacturers). The industrial units having high failure rate of electrical equipments i.e. Electric Motors (particularly smaller rating motors up to 7.5 HP), Bulbs, Tubes, Chokes, Contactor coils etc., should verify that it may be due to Higher Voltage.

TRANSFORMER : Introduction: A Transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits. Faraday's Law of Inductioniscovered in 1831 described this effect. Transformers are used to increase or decrease the alternating voltages in electric power applications. Since the invention of the first constant-potential transformer in 1885, transformers have become essential for the transmission,distribution and utilization of alternating current electrical energy. A wide range of transformer designs is encountered in electronic and electric power applications. Transformers range in size from RF transformers less than a cubic centimeter in volume to units interconnecting the power grid weighing hundreds of tons. History : Electromagnetic Induction, the principle of the operation of the transformer, was discovered independently by Micheal Faraday in 1831, Joseph Henry in 1832, and others.The relationship between EMF and magnetic flux is an equation now known as Faraday's Law of Induction: . where is the magnitude of the EMF in Volts and Φ B is the magnetic flux through the circuit in webers. Faraday performed early experiments on induction between coils of wire, including winding a pair of coils around an iron ring, thus creating the first torodial closed-core transformer. However he only applied individual pulses of current to his transformer, and never discovered the relation between the turns ratio and EMF in the windings. Types : Step Up Transformer : The Transformer in which Load Connected winding (Secondary Winding ) Voltage is greater than Source Connected Winding (Primary Winding) Voltage . Step Down Transformer : The Transformer in which Load connected winding (Secondary winding) voltage is less than source connected winding ( Primary Winding) Voltage.
Constant Voltage Transformer : Introduction : In our Ferro Resonant type Constant Voltage Transformers - CVT, the AC mains power the input winding, which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operate in conjunction with mains capacitor to produce self-generated AC flux Field which is indirectly extracted from the Input Winding. These Constant Voltage transformer or CVT use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output with a varying input. The ferroresonant approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage. The ferroresonant action is a flux limiter rather than a voltage regulator, but with a fixed supply frequency it can maintain an almost constant average output voltage even as the input voltage varies widely. All problems related to variation / fluctuation in Voltages are effectively handled because of this principle and a constant voltage output of ± 1% is given. Results : The ferroresonant transformers, which are also known as Constant Voltage Transformers (CVTs) or ferros, are also good surge suppressors, as they provide high isolation and inherent short-circuit protection. We are a renowned manufacturer of Constant Voltage Transformer and The Result of Constant Voltage Transformer - CVT are as under: 1. Instantaneous Voltage regulation. 2. No effect of input Transient and spikes on the output. 3. Sinusoidal output waveform. 4. A perfect answer and remedy for all types of electronic equipment. Our Constant Voltage Transformer or CVT have been manufactured to give you total protection against power related problems and to condition the power to suit the needs of your microprocessor based equipment. We are manufacturer of Constant Voltage Transformer which effectively regulates voltage variation, suppresses transients and bridges short interruptions/dips. Applications : Computers, Data Processing equipment, Colour Photography Labs., Bio-medical equipment, PA equipment, Telecommunication, TV, VCD/DVD recorders & players, Teleprinters, Fax machines and all other sensitive electronic devices. Why CVT ? We manufacture Constant Voltage Regulators which use a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output with a varying input. The constant voltage regulator approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage. Electronics instruments, Machines, Computers and other microprocessor based equipment are designed to operate on steady stream sine wave of 220/230 V RMS. The nature of utility power is such that very frequently the equipment encounter electrical disturbances and voltages which are beyond the range of those equipment. The quality of power has deteriorated so much during the past several years that today it is impossible to work without encountering disturbances. Equipment using microprocessors are especially vulnerable due to the degradation of the utility power. Thus in order to reach the equipment potentially damaging impulses generated outside your location travel through the impedances of lot of copper wire. Although this barrier serves to dampen out many of these disturbances the real problem occurs along the electrical path from the point the power enters your premises to your equipment. Between these points are all kinds of devices such as lifts, air conditioners, Fluorescent tube chokes, Photo copiers and in case of factories the machines. Any equipment that arcs, cycle on off, or draws excessive bursts of current becomes the cause of potential hazard to your micro processor based equipment.
