Depending on the length of time the interference processes are active, a distinction is made between short-term and long-term interference. Short-term interference is a rare occurrence resulting from a failure in a high-voltage installation... 

In a high-voltage installation it is important to avoid or reduce the electric stress which can result from abrupt termination of the insulating sheath or screen of the cable. Such conditions of electrical stress can... 

Overall the Institute was outfitted with more modern and high-performance equipment than most universities at the time. In addition to providing for standard chemical procedures, the laboratory furnishings enabled researchers to pursue a number of specialized lines of research - such as studies of thermodynamic constants in the constant temperature rooms. The apparatus at the Institute conformed to the latest standards in physical chemistry research. For example, the electrical equipment was the best available at the time, offering not only alternating and direct current facilities but also a high-voltage installation in the machine hall. Similarly, the Institute possessed apparatus for research at the extremes of available gas pressures and at the limits of spectroscopic precision. ... 

The performance of the gas solid interface formed is quite critical [3, 4]. It will determine the efficiency of the insulator in respect to the experienced service conditions and, furthermore, the reliability of the high voltage installation, considering that a single insulator failure is sufficient to set an installation such as a transmission line out of service for many hours.
