A Greek inventor with a long-standing experience in the field of sales and distribution of electrocution prevention devices, has developed an innovative leakage sensitivity controller that protects human life against electrocution and simplifies the installation with a plug-n-play interface. The inventor and his team are open to collaborations under manufacturing, joint venture and/or license agreements.



A small team of scientists from Greece led by a Greek inventor, who has over 30 years of experience in the field of sales and distribution of electrocution prevention devices, is offering an innovative solution, to further enhance the services offered by such a device. The inventor has developed a leakage sensitivity controller, whose primary role is the protection of human life against an electrocution by simplifying the installation with a plug-n-play interface.

The invention refers to the field of electronics / electrical equipment and relates to a device which applies the method, by which the amount of the electrical leakage of a circuit is detected, while regulating its leakage level in the electrical installation, in compliance with the global safety standards governing the electrical installations.

The use of this invention is to prevent the current from passing through a person’s body thus protecting his/her life, where voltage current up to 30V can cause a small shock, but larger ones may, under certain circumstances, even cause death. According to the present state of the art, for decades, the use of a residual current device (RCD) that interrupts the power supply in the event of an electrical current leakage, typically <= 30 mA, has been internationally decided. This amount of leakage, is the global norm for the smoothest operation with the less problems inside an electrical grid. The RCDs based on the Kirchhoff voltage law offer only supplementary protection. Since the passing of electric current through the human body is ruled by the law of Ohm: I = V / R and the current intensity depends on the resistance of the human body, which ranges from 5 kΩ to 100 kΩ, depending on the position of the body and the type of contact with the conductor, the safety limit is set to 10 mA. The application of the invention enables the amperage to be adjusted within the safety margin by eliminating the lethal hazard.

The long standing experience of the inventor in, installing, selling and distributing electrocution prevention devices in Greece and Cyprus, has given know-how and ideas on how to improve its function making its installation process much simpler, just by plugging it in a wall socket.

The team is looking for a partner to fund the production of the leakage sensitivity controller and take it to next step of concept/prototype in order to enter the worldwide market. The team is open to negotiate partnership terms a candidate partner has to offer under a license, manufacturing and/or joint venture agreement.

Advantages & innovations

Cooperation plus value: 
The present invention has the following advantages: 1. Energy is saved because the invention detects and measures the existing leak in the installation, enabling it to restore and stop the unnecessary leakage of energy in the circuit. 2. It achieves control of the reliability of the existing RCD because its application requires a gradual increase of the mA leakage of up to 30 mA to stimulate the RCD, according to the law governing safe circuit operation against electric shock of the condition of internal electrical installation, therefore any failure of the RCD is immediately perceived. 3. Detects the source of leakage and its intensity as early as 1mA. 4. The device is installed in all electrical installations connected to any electrical RCD and does not affect the functionality of the RCDs, even when improved RCD in response time (ms) are mounted in the circuit. 5. The 5 resistance levels and the total of 19 resistors of the device, placed on a large surface, on a board with inner layers of copper, help to keep the heat at low level. At the same time, the present invention distributes temperature in a better way, thus eliminating the use of fan, thereby rendering the device noiseless. Operation without fan eliminates the limitation of the life of the device. 6. In the logic circuit of the present invention the indicator is LCD type, resulting in lower power consumption. 7. Due to the supply circuit, which has the ability of lowering the voltage to 5V to operate the device, no radical change of the circuit is required in case the network where it is placed has a different voltage (220V / 110V), providing low cost materials for its production and less time needed. 8. Alternatively, the device can operate by adding infrared IR remote control or Wi-Fi remote control, to set the desired level of artificial leakage in the circuit through the world wide web.
