PDR-16 - Senkron Dengeleyici Analizörü

Zensol innovates once more with a new instrument, the PDR-16, ideal for the analysis of synchronous compensators.

This new instrument facilitates the diagnosis of all synchronous compensators in a simple, precise and affordable way.

The PDR-16 is used in conjunction with accelerometers, pressure, displacement, temperature and vibration transducers. The sampling rate varying between 30 Hz and 300 kHz makes it possible to capture a wide variety of signals with very slow evolution (ex: PID Loop) or with very fast evolution signals (ex: vibration).

The PDR-16 is bundled with a powerful and easy to use software: PDR WIN©. PDR WIN allows the standardization of tests during startup or reload service. In addition of integrating innumerable functionalities, it offers releases on events (trig) with the conservation of the preceding data.

"Electrical power transmission networks are protected and controlled by medium and high-voltage circuit breakers.

Breakers are meant to make and break the flow of electrical currents in transmission lines. Being so, the electrical contact function plays a main and critical role in the breaker's proper operation.

In the present article you will find a summarized description of the different types of electrical contacts used in power circuit breakers, the major risks to their proper operation and the principal tests used to verify their condition. "

"The interruption of electric power circuits has always been an essential function, especially in cases of overloads or short circuits when immediate interruption of the current flow becomes necessary as a protective measure.
 
In earliest times, circuits could be broken only by separation of contacts in air followed by drawing the resulting electric arc out to such a length that it can no longer be maintained.
 
This means of interruption soon became inadequate and special devices called circuit breakers had to be developed.".

« The first prerequisite for diagnosing breaker troubles is to know the breaker being analyzed. Knowing the configuration of the suspect apparatus' innards, it is possible to figure out the nature of the problem by visualizing the mechanical process of the operation, in perspective with the data of the timing test.

The same is true of the experienced mechanic who can determine, at a glance, the source of the mechanical problem in a car. He knows not only automobile mechanics as a general subject, but he knows the peculiarities of the model that is brought to him... »

Hareket Eğrisi :

« Whenever it is possible, a point-by-point measurement of the movement of the internal components of the circuit breaker, from the beginning of the movement until it comes to a complete stop, traces a curve called a DISPLACEMENT CURVE.

While the main contact timing curve gives the moment when the movement starts and the moment when the contact switches over, the information contained in the displacement curve is interesting because it allows us to follow the entire movement from beginning to end. »
