Transformer A transformer is a component or tool that we often encounter in electronic products, especially in power supply circuits and tube amp circuits. In addition, we also encounter many transformers in electrical distribution systems. Transformer Before discussing transformers, let's first discuss electromagnetic fields. If alternating current or AC flows in the coil or coil it will produce a magnetic field, this is called electromagnetic. Electrons that move continuously on an AC current produce an electromagnetic field, the resulting electromagnetic field also continues to move back and forth according to the flow of electrons that create it. Then if the magnet moves close to the coil or coil the magnetic field generated by the magnet makes the free electrons in the coil move, because the electrons move, it produces electricity, this is called electromagnetic induction. Electromagnetic and electromagnetic induction is the function of the transformer. Transformer or transfor...

Voltage In the previous post we have discussed a little about amperage. We already know that the ampere is a unit of electric current, the ampere is the number of units of electrons that flow to a point per second. 1A = 1 Coulomb of electric charge on electrons flowing per second Coulomb = Unit of electric charge In this post we will discuss a little about voltage or voltage, or often called voltage. By definition, the electric voltage is the energy/electrical potential difference between two points and is expressed in volts (V). Volt (V) = unit of difference in electric voltage Previously we discussed a little about the energy charge. Energy is measured in Joules (J). J  = V x C V = J / C Des : J = Energy unit         V = Voltage         C = Coulomb We analogize with bows, arrows & archers, if the archer pulls the bow with a force of 10 Joules (J), then the bow has 10 Joules of potential energy as long as the archer holds the bowstring a...

Current Or Ampere What is Ampere (A) ? Before we discuss further about current or amperage, we will first discuss a little about atoms. Atom Every object that is around us is composed of small particles called atoms, within the atom itself there is a nucleus and several electrons (negatively charged) that surround it. The nucleus itself consists of several protons (positive charge) and neutrons (neutral), this makes the atomic nucleus positively charged, while the electrons surrounding the nucleus are negatively charged. Atomic Movement Negative charges will push or repel other negative charges, while positive and negative charges will attract each other if they are close together. So an electron will push another electron if it can move freely. In objects such as wood and plastic electrons cannot move freely, so they cannot conduct charge or electricity. But in materials that conduct electricity, such as iron and copper, the electrons can move freely, while the nucleus is fixed. Elect...

Pnaumatic System Pneumatic comes from the Greek which consists of pneau which means compressed air and matic which means science. So in terms of pneumatic is a system that is used to move or move an object by using the wind as a source of energy. Pneumatic System Components 1. Compressor Compressore is used to suck air in the atmosphere and compress it in the compressor to a certain pressure then drain it into the compression system through a pipe or hose and enter the pneumatic system. Compressor 2. Bulk Liquid Separator Or Dryer Bulk Liquid Separator or Dryer is a part that functions to separate air from liquid so that the air entering the system is truly pure air. The way a Bulk Liquid Separator or Dryer works is by utilizing centrifugal force, namely the air rotates in a tube-shaped section so that the liquid will drop to the bottom and pure air or dry air will come out separately from the liquid. 3. Filter The filter serves to filter out dust and dirt in the air so that dust or di...

Bolier Boiler is a heat engine or thermal engineering that functions to transfer or convert chemical energy into work or business energy, more precisely a boiler is a tool to heat water to produce steam or steam. The heat energy from the steam is then used for various purposes, including geothermal power plants or other manufacturing industries. The heat from the combustion of fuel in the boiler will be transferred to the water media that flows in the piping system. When the water reaches a certain temperature, evaporation will occur and steam is formed. Boiler Types Of Boiler When viewed from the way it works, boilers are divided into 2 major groups as follows: 1. Fire Pipe Boiler Fire tube boiler is a type of boiler where hot gas passes through the pipes and boiler feed water is in the shell to be converted into steam. Consists of a water tank that is perforated and passed by pipes, where the hot gas flowing in the tank is used to heat the water in the tank. Heated water produces hot...

Building Air Conditioning System Function Maintain indoor temperature and humidity by absorbing heat in the room and blowing cold air. Various Types of Building Air Conditioning Systems The determination of the building's air conditioning system is determined by several factors, including the function of the building, the scale of the building (large/small), power usage, maintenance etc. 1. Chiller 1.1 Water Cooled Chiller Water cooled water chiller is a cooling system that uses water as a cold conducting medium and heat release medium. The water used is water with a normal temperature into the refrigerant where the temperature will be lowered to 8-12 degrees Celsius, then the water that has been lowered in temperature will be distributed by the pump to the AHU where in the AHU the cold water will cool the coil which will be passed by the air so that the air temperature when it enters the normal temperature will become cold air. The cold air will flow through the ducting or supply ...

Basic AHU System Planning Basic Problems The rapid development in various sectors of urban & industrial activities has a positive impact as well as a negative impact on environmental conditions. The negative impacts that arise are often realized only as temporary impacts from the development and development process, but in less than five years, it turns out that the environmental impacts in question have had a fairly large negative effect on various benchmarks of the quality of life of urban communities, which include the level of degradation of health and environmental comfort. The environment as a human habitation has a major influence on the behavior and habits of the people who live in it. Talking about environmental issues, then one of the things that can't be left behind is the issue of air. In areas that are quite densely active, air is a big problem that is quite a concern for regional leaders, one of which is DKI Jakarta as the capital city of the country, with its l...
