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 advantage that the transmitted power can be greater than a 1 phase system with the same conductor size and electric current. Therefore, from generation to distribution, this 3 phase system is used.

Neutral

Neutral is the part of the conductor or conductor of electricity that has no voltage. The function of this neutral is as a return path for electricity to the source and as a reference voltage of 0 V.

Both Phase and Neutral are sourced from PLN or other power plants. In power generation systems, usually this neutral is grounded or grounded.

Ground

In the previous post we have discussed this grounding system, so you can see at the following link,

Thus my brief discussion of the difference in phase, neutral and ground. May be useful.

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
