services in the field of grounding systems, interference and line parameter calculations and support our clients in the following areas, among others:<\/p>\n<ul>\n<li>Design of grounding systems<\/li>\n<li>Evaluation of Ohm\u2019s influence on transmission towers, cable joints and other high-voltage technology systems<\/li>\n<li>Inductive interference analysis of pipelines, telecommunication lines, etc.<\/li>\n<li>Calculation of line parameters of overhead lines and cables (including untwisted and asymmetrical ones)<\/li>\n<li>Calculation of the chain conductor and the earth wire or cable shield reduction factors, even in complex arrangements such as discontinuities (e.g. overhead line to cable) and in parallel systems<\/li>\n<\/ul>\n<p>We offer numerous measurements to support this, such as:<\/p>\n<ul>\n<li>Measurement of the specific grounding resistance using the four-probe method (Wenner, Schlumberger, dipole-dipole etc.) according to EN 50522 or IEEE Std. 81, if necessary with inversion to multi-layer models<\/li>\n<li>Measurement of grounding impedance, grounding voltage and compliance with touch voltages at grounding systems such as substations, power plants and electrical pylons according to EN 50522 or EN 50341<\/li>\n<li>Measurement of the line impedances of overhead lines and cables<\/li>\n<\/ul>\n<\/div><\/div><\/div><div
