New content on Ultra Rapid circuit breaker

UR figure 4.jpg
As installed power increases, electrical distribution has to shift from a LV design to a HV design. Indeed, a high short-circuit level can be a threat to the installation and make impossible the selection of low voltage equipments (Switchboard and bus bars, circuit breaker…)


These situations can be met in the following applications:
Bus bars coupling onboard merchant vessels, off shore platform, loop networks (in industry), where the current and energy are important because of the installed power (several transformers or generators in parallel) and HV design not easy. <more>

Electrical protection against surges

Highlight foudre.jpg

6 pages dedicated to electrical protection against surges have just been fully updated.
In addition to describing the operation of the surge arrester, the emphasis is on the method of choice and their location in the architecture of the electrical installation. Similarly the security of the facility is an essential element; coordination table between the arrester and its short circuit protection device is proposed. This is the result of extensive studies and tests in laboratories conducted by specialists which expertise is about short circuit breaking and lightning electromagnetic phenomena.
