  ELECTRIC SOCKET
In the newly-proposed design, one of the contact element ends is made as a fork-shaped part. In every cavity of the housing bottom two through holes are made; the two holes are projected on the housing bottom rectangular passages made on the inner side, wherein contact fork tail ends and wire ends can be inserted.

  SAFETY DEVICE FOR A DC CIRCUIT
The newly-patented device includes a DC source and a controlling safety unit (CSU). The first inlet port of the CSU is connected with an outlet port of a meter; the outlet port of the CSU is linked with a safety device to switch off a regulating circuit. The second inlet port of the CSU is connected with a power source. Unlike protection systems available on the market today, the new system is equipped with a transformer and diodes incorporated between the buses of the regulating circuit. Diode is connected through cathode with a positive bus of the regulating circuit and through anode with the first outlet of the transformer secondary winding. The second outlet of the transformer secondary winding is connected with a negative bus of the regulating circuit.

  ELECTRIC ARC EXCITATION TECHNIQUE AND EQUIPMENT REQUIRED
The proposed technology differs in that after the short-circuit current reaches the magnitude of the stable arc current level, a turn-on voltage of the same polarity exceeding the power source voltage is fed across the output of the power source, then the arc gap is fed with a reverse polarity delayed excitation voltage pulse of shorter front duration whose nominal value exceeds the turn-on voltage.
