Permanent overvoltage protection
Permanent overvoltages, also called temporary overvoltages, are caused by a voltage rise above 275V for an undetermined time. The absence of a neutral or a failure of the medium voltage transformer may be some of the causes.
These surges cause damage and destruction of equipment, premature aging and reduced user safety.
Due to the decrease in component size, equipment protection is now even more necessary.

unpredictable surges
Transient overvoltage protection
Transient overvoltages are characterized by a rapid and sharp increase in network voltage, typically triggered by atmospheric phenomena like lightning, or even switching operations within the electrical grid. These sudden spikes can inflict severe damage, leading to the deterioration and outright destruction of equipment, causing malfunctions, significantly reducing useful life, and resulting in interruptions to user supply.
Fortunately, protective devices called Surge Protective Devices (SPDs) offer a crucial defense. When an SPD is installed, it effectively shunts this excess energy to the ground, thereby limiting the voltage peak to a level that the electrical equipment connected to the network can safely withstand.
the perfect surge protection combination
Permanent-transient overvoltage protection
At Toscano, we deeply understand the critical need for robust protection against both transient and permanent overvoltages. That’s why we’ve engineered a dedicated product line designed to safeguard your electrical systems from both types of damaging surges.
Our solutions offer effective and highly reliable protection. These are compact, combined units that feature pre-wiring, significantly cutting down on assembly time and making installation a breeze. Plus, our innovative system allows you to replace only the worn or defective component, so you don’t have to swap out the entire unit, saving you time and money.

questions and answers
Frequently asked questions about surge protection
What types of surges are there?
There are transient overvoltages, which are brief, rapid increases in voltage, and permanent overvoltages, which are sustained increases over a longer period of time.
How do Toscano devices protect against surges?
Toscano's devices divert excess energy to ground in the case of transient overvoltages and cut off the supply in the case of permanent overvoltages, thus protecting the connected equipment.
What products does Toscano offer for surge protection?
Toscano offers a range of products including transient, permanent, combined and lightning protection surge protectors.
What is lightning protection and how does it work?
Toscano's lightning protection includes electronic priming devices that protect buildings and people from direct lightning strikes by means of a triple safety system.
Why is it important to protect installations against surges?
Protecting installations against surges is crucial to prevent damage to equipment, ensure its efficient operation and prolong its service life.
How can I calculate the level of lightning protection required for my installation?
You can use Toscano's free online tool T-Storm, which calculates the level of protection required according to various international standards.
