Fundamental characteristics of circuit breaker
Apart from small circuit breakers which are very easily replaced, industrial circuit breakers are equipped with removable, i.e. exchangeable, overcurrent-trip relays. Moreover, in order to adapt a circuit breaker to the requirements of the circuit it controls, and to avoid the need to install over-sized cables, the trip relays are generally adjustable.
Rudolf Diesel
Dr. Rudolf Diesel boarded “SS Dresden”, a cross-channel ferry, at Antwerp in September 1913. He was going to see the newest diesel engine factory of London. The famous engineer was invited as a guest of honor to the opening of that factory. He was traveling alone. After dinner Rudolf Diesel went to his cabin at about 10 p.m. and that was the last time anyone saw him alive. His cabin turned out to be absolutely empty next morning on September, 30.

Internet der Dinge
Die Digitalisierung ist weder aus der Geschäftswelt noch aus dem Privatleben wegzudenken. Doch wie ist der Status quo bei der Nutzung sogenannter vernetzter Geräte tatsächlich – abhängig von Alter, Geschlecht, Technikaffinität? Und in welchem Maße sind Trendthemen wie das „Internet of Things“ (IoT) schon in der Verbraucherpraxis angekommen?
Current and voltage sensors as an alternative to traditional CTs and VTs
As an alternative for traditional primary current and voltage measurement techniques, the use of sensor technique is gaining field. This technique is typically applied to current and voltage measurement in medium-voltage metal-enclosed indoor switchgears.
