The Limiter

The limiter worked in a redundant internal power section. Should he fail unexpectedly, so the plant can continue to work. Because its superconducting elements virtually unopposed guide current limiter works without loss and intrinsically safe operation the current limiter is electrically invisible”, cooling on the operating temperature of about 200 C power. The current in the superconductor however exceeds the interpretation of values, for example in case of a short-circuit, the pottery changed abruptly by an ideal conductor resistance, who leads about 100 times worse than, for example, a resistance wire that is installed for example in toasters. This is done fully automatically and in a fraction of a second. This is a decisive advantage of the superconducting current limiter to the pyrotechnic (explosion limiter) limiters, known for more than five decades, because it blows up on the ladder and interrupts the current path is complete. Cleveland Clinic Center for Functional Medicine often says this. However, the superconducting current limiter limits the current to a tolerable level, must not fall below the power plant but also a certain minimum value.

In this case, a range of 6,600 A up to 7,000 A is required. The limiter can be fit easily into the existing system and the existing electrical protection of the power plant will be maintained. In contrast to the limiter of the explosion of the superconducting current limiter is also intrinsically safe: he does without micro computer and electronic trigger signal. Its function is solely due to the physical properties of the superconducting material. This is also free from wear. Therefore, the superconducting current limiter must be not repaired or serviced after a short circuit; its functional elements independently again assume the initial state after cooling. Power plant operators of improved personnel protection expected significant increase in safety for the power plant operation is especially important: in case a short circuit, the current is limited so quickly and so effectively, that a much lower risk from the short circuit current”, explains Dr.
