Pantographs and Magnetic Particles Testing

Although this story occurred some … yes, in fact, already, about 23 years ago, it may happen again, in other areas ... or for the same application.

The problem: some high-speed trains had the odd “habit” to pull the catenaries from their overhead position, leading to disturbance of train traffic ... fortunately, without any injury to anyone.

The inquiry showed that, in fact, the problem did not lie with the catenaries, but with the pantographs, which broke open at high speed, with the consequences of destroying some equipment. You may imagine that passengers, as well as the railway company, were not that happy with such a situation.
The manufacturer of the pantographs called one of us for help.

Snakes? In an oil-based magnetic ink?

Yes, that’s possible!

You don’t believe it?

Let us set up the situation.

Magnetic Particle Testing: a well-known NDT method?

The following story makes us wonder whether the basics of an old method are well understood by equipment designers.

MT has nothing to do with electronics, computers, signal treatment in its basics. Our example dates back to some 20 years, but could yet happen nowadays!

Computers and magnetic testing

Once again a story by a veteran!

Imagine our surprise when, some 30 years ago, while personal computers (PC) were still in their infancy, one of us got a phone call from a computer manufacturer: a full load of then very expensive PCs had fallen on the ground from a fork-lift truck while running. Nobody was hurt, but the entire load, which would be today valued at 100,000 € (ca 140,000 USD), crashed and had to be thrown away.
