Symbol Standart P&ID

    Symbol Standarisation P&ID For Industri Standard piping and instrument symbols are detailed diagrammatic documentation that provides a set of forms & standards for documenting P&IDs and PFDs, including standard shapes for instruments, valves, pumps, heat exchangers, mixers, crushers, vessels, compressors, filters, motors and other connection forms. Here are some symbols on P&ID : So, those are some of the symbols that we will often see when reading piping & instrument diagrams. May be useful.

Why Humans Can Get Electrocuted

What are the causes and how does the human body feel when electrocuted?


In previous posts we have discussed a lot about electricity, but have we ever thought what would happen if the human body was electrocuted and what causes the human body to be electrocuted?

Many conclude that our bodies contain a lot of water so that our bodies can be good conductors of electricity and where our bodies hit the electrical wires when our feet touch the ground we will be electrocuted or electrocuted. But actually this is a somewhat wrong opinion, when our feet are not on the ground, we can still be electrocuted if we come into contact with a power source.

So what causes our bodies to be electrocuted?

Another opinion states that the human body contains neutral voltage electricity, for example when we connect an electrically charged cable or phase with a neutrally charged cable, a short circuit will occur. Similar to the human body, a neutrally charged human body when in contact with a power source will cause a short circuit. This is what causes us to be electrocuted.

So what happens to our bodies when we are electrocuted?

When our bodies are electrified, it will disrupt the organ systems in the body, among others, it can affect the muscles, a little additional information, muscles, tendons, ligaments can work because of the exchange of ions and small amounts of electrical energy.

The second, electrocution can cause heart failure, just like the body's muscles, the heart also has muscles that work because of impulses in the form of electrical energy. If our bodies are electrocuted more than 50 mA, the energy will disrupt the rhythm or rhythm of the pumping of the heart and then fail to meet the needs of blood throughout the body.

Third, being electrocuted can cause bodily injury, injuries caused by electrical energy are classified as burns but are different from burns from fire.

The last is that it can damage the nervous system. Talking about the nervous system, this is the system that is most closely related to electricity. When there is electricity from outside that enters the body, the energy will affect the electrical conductivity of the nerve cells and will make us feel pain, numbness and even difficulty moving parts of the body that are affected by electrical energy.

Text And Mtext In Autocad

The Difference Between "Text" And "Mtext" In Autocad And How To Convert It In operating AutoCAD we often encounter or use writing with the aim of providing information, showing something, etc. so that our drawings are easier to understand. To write in AutoCAD, we know that there are two options, the first is "TEXT" and the second is "MTEXT". So what are the differences between the two? TEXT For "text" itself we can call it single text or single writing. So if we use "text" we can only write one sentence in one piece of text. The disadvantage of this "text" is that it doesn't have any editing menu, we can't adjust or adjust our needs in this paper, instead we must first enter the properties menu. This means that from this "text" we can only edit the written content. To use this "text" we can use the command type "DT" then press enter. MTEXT As for "mtext" itself is an ab

Genset Heating Procedure

Genset Heating Standard Procedure Genset is one of the equipment that functions to convert mechanical energy or rotation of the rotor into electrical energy. The generator has two main parts, namely the motor generator and the generator engine (usually a diesel engine), both of which are connected by a shaft. The generator itself has two main parts, namely the rotor and stator. The stator is the stationary part, while the rotor is the rotating part. This generator works when the genset control panel receives input if the power source from PLN dies, then the PLC or ATS (automatic transfer switch) will give an order to the genset control panel to turn on the generator, this is done automatically. What if the generator has to be turned on manually, for example when heating the generator? Genset as one of the supporting utility facilities of a building must of course be maintained regularly, one of which is heating the generator as one of the genset maintenance procedures. To warm up the g

Neutral Ground Phase Difference

In electrical distribution systems, especially AC current for low voltage electricity, we often find terms around phase, neutral and ground. What is the difference between these terms? Let's discuss them one by one. Phase For low-voltage electric current, the term for low-voltage phase is divided into 2, namely phase voltage 380 V and voltage 220 V. Before we discuss further about low voltage, let's first discuss what a phase is. Phase is part of the conductor or conductor of electricity that contains voltage. The difference between the 380 V and 220 V voltage is that if the 380 V voltage uses 3 conducting wires or other terms 3 phases, the 220 V voltage only uses 1 conductor cable or other terms 1 phase. The voltage of 380 V is obtained from measurements between phases with other phases, while the voltage of 220 V is obtained from measurements between phases and neutral. This measurement is carried out using a multitester. The 3 phase system was developed because it has the ad
