What can I do to protect my equipment from overvoltages?
Fortunately, the devices can be protected against voltage surges with a device called surge arrester. Although surge arresters do not always protect against lightning, they will protect the equipment from overvoltages for the other reasons mentioned above.
What are overvoltage protection devices and how do overvoltage protection devices work?
As the name implies, a surge-protector is a device that protects and protects your devices from overvoltage / peak voltage (hence the peak current). Many people use surge protectors to power desktops, televisions and so on. When the voltage rises above a certain level, the over-voltage protection blocks or transfers excess energy to the ground. This ensures that the connected devices are not affected or interrupted by an increase.
How many joules do you need for good overvoltage protection?
You want to protect your equipment, but you do not always want to buy a new surge-protector if you protect it.
If you use one that has a very good joule, it should take many breakouts and pimples.
I suggest a rating of over 3000 joules. A little less and your surge-protector can not survive a peak. Your device may not be protected if you receive more than one high voltage notice before replacing the surge-protector.
Overvoltage protection with a low Joule value can be destroyed by a single high voltage spike. These cheap protectors must be replaced frequently. You end up saving more money in the long run by getting a good Joules surge-protector to get you started.OHSH611 HOUSE Telephone Surge Module You can check price OHSH611 – OPEN HOUSE H611 Telephone Surge Module
