Electrical Power Substation - Type of Electrical substation

Electrical Substation Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations may be hydro-electric, thermal or atomic. Depending upon the availability of resources these stations are constructed different places. These places may not be nearer to load centers where the actual consumption of power takes place. So it is necessary to transmit these huge power blocks from generating station to their load centers. Long and high voltage transmission networks are needed for this purpose. Power is generated comparatively in low voltage level. It is economical to transmit power at high voltage level. Distribution of electrical power is done at lower voltage levels as specified by consumers. For maintaining these voltage levels and for providing greater stability a number of transformation and switching stations have to be created in

The voltage stabilizer shows over voltage or under voltage how to deal with?

Usually the power distribution voltage is not 230V, 400V, the low three-phase power is more than 200 volts, the high one is 400 volts, and the single-phase power is the same. The high and low voltages sometimes differ greatly, so before we buy the  voltage stabilizer , we need to have a measurement on the electrical sample used. The  v oltage stabilizer manufacturers   will set the minimum and  maximum voltage value of the user of the voltage stabilizer according to the electrical sample, and then obtain the fluctuation range value of it. Then according to the obtained the output voltage fluctuation value indicates the most suitable voltage stabilization range of the voltage stabilizer, and generally, when choosing the voltage stabilization, the voltage stabilization range of the voltage stabilization range is wider than the actual range. Regardless of the regulator produced by the regulator manufacturer, no matter what type of regulator, there will be some voltage stabilization range.

How to choose a 3 Phase Stabilizer?

First of all, it depends on the type of your electrical equipment. Generally, the load is not purely resistive. Therefore, in practice selection, the stabilized power supply should be selected reasonably according to the details of the additional power, power factor and load type of the electrical equipment, and its output power should be left with appropriate margin, especially the margin for impact load selection. To be bigger, how to choose the  3 phase stabilizer  is as follows: ⒈ For pure resistive loads such as incandescent lamps, resistance wires, electric furnaces and other equipment, the power of the three-phase regulator should be 1.5 to 2 times the power of the load equipment.   ⒉ Rational and capacitive loads such as fluorescent lamps, fans, motors, water pumps, air conditioners, computers, refrigerators, etc. The power of the three-phase regulator should be 3 times the power of the load equipment.   ⒊ Under the environment of large electrical rationality and capacitive

Copper vs. Aluminum Dry Type Transformer Windings

Dry type transformers typically feature either copper or aluminum windings, also known as coils. Transformer windings refer to the coils within the transformer that draw and distribute power inside the unit. There are typically two windings in a dry type transformer — one that draws power from the source and another that transfers that power to the load. Both copper and aluminum windings perform the same function. For some applications, one type is preferable over the othe r. The   option you choose depends on the specific needs of your facility and your unique requirements. We’ll explain more about how aluminum and copper windings compare below. Differences Between Copper and Aluminum Windings While most low and medium voltage dry type transformers rely on aluminum windings for energy transfer, many engineers and plant operators prefer copper windings for specific applications. Here are some of the primary differences between the two types: Initial Costs At the outset, aluminum windin
