NEW WAYS TO INTEGRATE GROUNDING, EQUIPOTENTIAL BONDING, SHIELDING AND LIGHTNING PROTECTION
KOMUNALNA ENERGETIKA / POWER ENGINERING, 14
The safe and reliable operation of electronic equipment in modern low-voltage electrical, suitable for bidirectional energy and information flows, requires - starting from the transformer stations via the mains connection to the location of the equipment in the buildings - special attention with regard to the integration of grounding, equipotential bonding, shielding and lightning protection. As these themes so far in the planning, implementation and verification are considered mostly separately, in practice a variety of electro technical problems such as with stray currents, unwanted interference fields and inductive interference caused by low-frequency and transient currents result. In the following article new and old methods for a functional, comprehensive approach to planning and construction of electrical installations are combined, which takes into account the needs of various grid-bound supply systems such as electricity, gas, water and telecommunications.

SELECTION OF A SUITABLE CONDUCTOR FOR GROUNDING THE CABLE SHIELD TO THE TRANSMISSION LINE TOWER
KOMUNALNA ENERGETIKA / POWER ENGINERING, 16
This paper describes which factors to consider when faced with choosing conductor for grounding of surge arresters and high-voltage cables on powerline construction, where transition between powerline construction and powerline cable takes place. For proper grounding of surge arrester and shielded cable, the grounding cables have to be designed to ensure efficient high frequency current flow to the ground that can reach up to 10 kA. During our research and measurements we have chosen such a conductor that at the same time ensures recommended parameters and is not of any particular value to vandalism.
