On the one hand, in carrying
out our daily activities, we really need tools as help as well as generators.
but on the other hand, generators can be very dangerous to our safety if not managed properly, for example, running a generator that is not suitable in wet conditions. Most people have experienced / felt
electric shock, from those who just feel surprised to those who feel very suffering. Therefore, to prevent unwanted things from running generators when wet, we need to increase our awareness of the dangers of electricity and the best way is to increase our understanding of the basic properties of electricity that we use, or choose the right generator when we want to use it. in wet conditions or outdoors.
but we don’t discuss which generator is right, but Can a Portable Generator Get Wet?
so check out this article.
There are a number of things to look out for before using a generator
when wet, here are a few things.
Carbon monoxide (CO), which needs to be considered in the use of generators when wet is the CO content of smoke released from the exhaust generator which can cause poisoning. Errors in the use of generators when wet can cause users to get CO poisoning, it must be avoided because the content of CO can cause things that are not desired if it has poisoned the user or operator of the generator because it can cause serious illness and even death. Because CO does not smell and also not seen this usually occurs when the generator is run when wet, in order to avoid CO poisoning, detector CO is needed. It will be able to give a warning if CO has increased. It is better not to use a generator in a room such as a garage or outside near a window or air vent that can cause the generator to get wet or allow CO to enter the room.
It should be noted also to always maintain the flow of air coming out of the generator. If you use a generator when wet for an emergency power source in your home, if when the generator has been turned on and then you start feeling like dizziness, flu symptoms or pain. Hurry up to get out of the room immediately, because there is a possibility that something wrong in the air in your room is caused by a generator.
Electric shock from the generator
Electric shock from a wet generator will be felt if electric current through our body. In small currents, current will only cause tingling or loss of the ability to control the hand. At large generator currents, electric current can burn our skin and flesh. The most dangerous thing is if the flow from the wet generator flows through the heart or brain. It should be noted that what is dangerous is the flow of electric current, not electricity. Even though the generator voltage is high, it may not be dangerous provided the current is very small.
Heat or fire.
Heat arises because of the flow of current through a resistance. If we use a generator when it is wet, the resistance is large so the generator can warm up. Wire from a hot generator can cause cable insulation to burn resulting in a short circuit. Imperfect contacts or connections can also cause heat that burns generator cable insulation.
So it is obviously very dangerous to use a generator when it is wet.
When there is a short circuit, the flow of electricity will be very large. Very large currents can cause a very rapid rise in temperature, causing rapid air pressure to rise, which occurs when you use a generator when wet. For residential installations, this danger may not be too large because the short circuit that might occur is not too large.
But before you operate your generator in a wet state, there are things you need to consider the following.
because it does not mean using a generator when wet can be blaring, because in the human body also has certain electrical / volt conditions.
see the following.
Sometimes we think why a voltage of 220 V at home can cause death, while a 12V battery voltage is okay if held. Well, this is due to our body’s resistance to electricity which when measured is 1200-5000Ohm. So with the formula below, it can be obtained how much electricity flows in the human body.
Electric current = Voltage: Prisoner.
The heart as the body’s organ which is most susceptible to the influence of the flow of electric current senses in four limits:
Area 1 (0.1 to 0.5mA): the heart is not affected at all even for a long time.
Area 2 (0.5 to 10 mA): the heart reacts and a tingling sensation appears on the surface of the skin. Above 10mA to 200mA
the heart lasts for a maximum period of 2 seconds. (Depends on conditions)
Area 3 (200 to 500mA): The heart feels a strong and painful shock, if it passes 0.5 seconds into the danger area.
Area 4 (above 500mA): the heart will be damaged and can permanently damage the circulatory system and even result in death.
Thus, based on IEC60479 by considering several parameters such as: the duration of electricity passing through the body, the place of touch, the part of the body flowing, the conductive form held and the psychological effect of a person determined that 10 mA can pass through the human body indefinitely. Return to the formula above then:
Safe Voltage = Electric current that is allowed The resistance of the human body
Then the safe voltage is 10mA X 1200Ohm for wet conditions and 10mA X 5000 Ohm for dry body conditions
Obtained safe voltage without time limit for alternating current is:
- Dry conditions = 50 Volt
- Wet conditions = 12 Volts
Whereas the safe voltage without time limit in the direction voltage is:
- Safe voltage dry conditions = 120 Volts (separate explanation)
From the explanation above, the
residual current protection wire that must be installed at home is: 30 mA.
Likewise, why does the generator run when wet using 12Volt.
Make sure there is no more reason to install ELCB or DPNa at home with 30 mA for sockets and 300mA for fire protection on generators that can make explosions or fires in your home.
Do 7 of these for anticipation
1. Stay away from bare ends of the cable, especially when your generator is wet, if you don’t know if the cable is voltage. Ask for help from an electrician or use a tool such as a tespen to test whether the generator cable is voltage. He usually uses the help of a test pen to test it before you hold your generator.
2. When plugging electricity into a wall socket, make sure your hands are dry. If it’s still wet, dry it until it’s completely dry.
3. Replace the chipped cable or the socket that is almost detached from the wall. This can prevent you and other occupants from being electrocuted while plugging electricity into your generator socket.
4. Install carpets, rubber pads or soften rubber shoes or sandals when plugging the electricity into the socket. This method can prevent the danger of electric shock from a wet generator because there is no electric current flowing in the body.
5. The water outlet is not splashed? Avoid using it until the socket is completely dry. You can also use a dryer to dry it. To keep the wet socket from being used by other residents, you should close it with insulation.
6. Just use one stop per per plug. That way you can prevent the short circuit from burning your generator.
7. If you have a small baby, attach the socket at a distance of at least 1 meter from the floor so he cannot reach it. Small children are usually curious and like to pick up your socket or generator.
That’s seven ways to avoid electric shock when your generator is wet, which you can practice.
Choose a generator that is suitable for the rainy season
Hold in hot or rainy weather
For example, the cummins 250 kva silent type generator set where the silent generator is generally a generator placed outdoors. But you have to make sure that your generator box is waterproof, especially on the outside of the engine so it doesn’t damage your generator engine.
Hold in hot or rainy weather, This silent generator in general is a type of generator that is placed outdoors so that the silent generator has resistance to hot weather and rain. But you still need to make sure that your box canopy generator is resistant to water so it doesn’t damage your generator engine.
Easy machine maintenance
Like other machines that are around us, the silent generator engine also requires maintenance where the maintenance must be done regularly. But you are calm, because the maintenance of the silent generator is not difficult.
and with a silent generator, you don’t need to hesitate in running the generator even when it’s wet.
Three determinants of running a generator when wet.
There are three important factors when running a generator when it is wet, namely: large currents, flow paths, and the length of the generator is wet.
The amount of current from the generator will be determined by the voltage and resistance to wetness. The voltage depends on the system voltage used, while the generator resistance varies depending on the type,
and other factors such as watts, volts and so on. Generator contact resistance varies from 1000 k-ohms (dry state) to 100 ohms (wet state). Internal generator internal resistance between 100 – 500 ohms.
If the system voltage used is 220 V, what is the probability of danger if used when wet?
The worst conditions:
– The generator resistance is the contact resistance of the generator plus the internal resistance of the generator, (Rk) = 100ohm + 100ohm = 200 ohms.
– Flow that flows when wet: I = V / R = 220 V / 200 ohm = 1.1 A
– Rk generator resistance = 1000 k-ohm
– I = 220 V / 1000 k-ohm = 0.22 mA.
- The flow of current in the generator when wet
The trajectory of electric current in the generator will also determine the level due to electric shock. A very dangerous trajectory is the one that passes through the heart, and the nerve center (brain).
so you have to be very careful
Use the Generator in accordance with the Rules
As a primary need for urban
communities, the use of generators used by almost all homes does require
serious attention from customers and responsible companies. All devices used
should have licensed installation standards on generators as well as devices
used by their customers. Unfortunately there are still people who do not know
the dangers of whether or not to use a generator when wet or any generator that
is appropriate to use, this is obviously very dangerous for you and your
neighbors because it can cause shortages and fires.
so it’s very important to understand the generator and choose the right generator.
Sometimes customers also cause many cases of fire due to short circuit generators due to carrying out generators when wet, for example the transfer of illegal electricity that often happens around us because besides harming the state this activity also causes losses on the part of the community. With the occurrence of these cases, there will be a very possibility of a fire caused by a short-circuit of sparks from the generator when wet.
It is important to ensure that the generator in your home is safe, starting from Kwh meters, volts and other voltages.
