A source of danger for the operator may be constituted by an excessive current of dispersion to the ground produced from anti-shock capacitors.

Experimental tests conducted on the human body have defined the rising values ​​of current which statistically most of the population can appreciate up to the dangerous values ​​for tetanus and ventricular fibrillation.         
Especially the equipment they must ensure the absence of such dangerous currents even in fault conditions such as disconnection of the protection, polarity exchange, an external voltage dangerous on the wrap and so on.         

"Dispersion current" means undesired current which, by a fault-free electrical circuit, flows to the ground directly by its mass connection or indirectly by means of conductive elements such as the casing, part of the machine or a person touching it the casing.         
The dispersion current is also often referred to as "current in the body".

A safety test on the electrical equipment must be completed at the end of the control and disconnected device by measuring the dispersion current at high rated voltage, always in compliance with the current test standards.         
For electrotechnical equipment only the leakage current test allows the activation of the internal circuit elements.         

Our laboratory performs all types of tests to verify the correct isolation of any electrical / electronic device based on EN 60950.
