Galvanic isolation, without going into too many technicalities, is a subject that is already much discussed and yet there are people who are not very clear about what this term refers to. Summarizing the answer, galvanic isolation is composed of two words, isolate and galvanic. It is a reaction that occurs when you put in contact different metals such as copper with aluminum or copper with steel (and its derivatives).

As for the galvanic current, it is produced by contact between two metals, usually by the environment or in saline environments. There are means to reduce this effect and a lot of information can be found about it.

This is another definition: a type of current that, in addition to being continuous, is uninterrupted and of constant intensity. This current is called galvanic. In terms of its physical characteristics, galvanic current is low voltage (60-80 V) and low intensity, maximum 200 mA. It is also called constant, because it maintains its intensity fixed during the time of application.

The differential circuit breaker is part of the electrical installation of all dwellings. It is intended to protect the dwelling (apartment or house) in case of overvoltage. It also protects the electrical equipment in the house. If you want to know all about GFCI, read on. You may also be interested in:

A differential circuit breaker is a bit like a general switch that would cut off the electrical circuit in case of a problem. The current becomes dangerous when it exceeds 50 mA. The circuit breaker turns it off as soon as it detects a current leakage greater than 30mA to mitigate electrical risks due to an insulation problem. It is there to protect your electrical installation very effectively. It is inseparable from all electrical circuits.

It works as follows: comparison of differential current entering the installation with the one leaving it. When the difference exceeds the value, called sensitivity, which is expressed in milliamperes or mA, the differential is cut.

An isolation switch is part of an electrical circuit and is most often found in industrial applications. The switch does exactly what its name suggests, as it electrically isolates the circuit or circuits that are connected to it. Such a switch is not normally used as an instrument to turn the circuit on/off in the way a light switch does. It is unloaded or without a charging device. It is mainly found in heavy industry. It is operated to disconnect the electrical system from the main supply for maintenance activities. It is an additional safety device. The trapped load will be grounded through its ground terminal. It is usually placed after the circuit breaker.

How to detect electric current leakage

You are cooking peacefully, you turn on the oven and suddenly, the power goes out! You go running to the electrical panel. What could have happened? If you have already ruled out that it is an excess of electrical power, it is possible that it is the differential. In Gana Energía, we want to analyze why the differential of the light jumps and the steps to follow when the differential jumps.

Another reason why the differential jumps for no apparent reason is that an appliance is channeling high frequency harmonics in the network. In addition, it is also normal that the differential jumps the differential by storm because the humidity increases.

Now we will analyze the main reasons why the differential jumps and what to do if the differential jumps. Remember that in Gana Energía we are energy advisors and we offer you our electricity and gas supply rates and the best tips to optimize your electricity costs.

There are several causes that explain why the electricity differential jumps. As we said, the differential jumps when it detects that part of the current goes out of the circuit. This deviation produces a difference between the current that it injects and the one that arrives at the end of the circuit. Then, the differential is triggered. When does this happen?
