Dirty electricity

Dirty electricity, also known as electrical noise, is a form of electromagnetic pollution present in electrical power networks. In this category you will find solutions to measure and reduce dirty electricity through dedicated meters and electrical filters.

What is dirty electricity?

Dirty electricity, or electrical noise, is caused by irregular spikes, harmonics, and voltage surges generated by electrical and electronic devices connected to the power grid. These phenomena occur when equipment needs to convert or regulate electrical current in order to operate.

As a result, this type of electromagnetic pollution spreads through the wiring of buildings and homes, where ideally only stable alternating current should be present.

How dirty electricity is generated

Many modern electrical devices—power supplies, chargers, electronic systems, and equipment with power electronics—manipulate electrical current during operation. This process generates interference that travels along power lines, spreading throughout the entire installation.

Dirty electricity can cause electromagnetic interference that affects the optimal performance of electrical appliances and sensitive electronic systems, especially in environments with a high density of connected devices.

Products to measure and reduce dirty electricity

Measuring dirty electricity

• Dirty Electricity Meter: a broadband device that allows the detection and quantification of dirty electricity on the power grid, as well as comparison of levels before and after applying filtering solutions.

Reducing dirty electricity

• Dirty electricity filter: designed to reduce electrical noise present in residential and building electrical circuits (availability subject to stock).

Importance of measuring and controlling dirty electricity

Controlling dirty electricity makes it possible to assess the condition of an electrical installation and detect the presence of unwanted interference. The combined use of a meter and a filter enables an objective, data-driven approach to improving the electrical stability of the environment.

These solutions are especially useful in residential buildings, offices, environments with sensitive electronic equipment, and spaces where a cleaner, more controlled electrical network is required.
