Exhibitor details

Jörg Harz Elektrotechnik is a typical master craftsman's business for electrical engineering.
The company is based in DE 07774 Camburg-Thüringen, Marienplatz 2.
His main field of work is electrical installation in the Jena area of Thuringia.

The master craftsman became an inventor through customers who suffered an electrical leakage. They wanted to hold him liable for this, even though he could not have been held responsible. Jörg would be a bad master craftsman if he didn't have an answer or solution to these problems.

Before he presented the solutions, they were registered with the German Patent and Trade Mark Office (DPMA). After that, however, other problems came to light. They already exist in similar forms and are lying dormant in drawers. Nevertheless, they are not used.

Due to the standards, manufacturers do not want to adopt his inventions so easily. Even though they consider it absolutely necessary.

Why categorised into three groups?
My inventions were born out of necessity. Sometimes the previous invention led to another one. In retrospect, these inventions can be divided into three groups.

Group 1: Missing protective conductor
Group 2: Separation of protective conductor and leakage currents
Group 3: stray voltages, currents and frequencies
