37、 in 1948, power system control and protective relays were almost exclusively electro-mechanical. There were a few special applications, such as automatic synchronizing of ac generators, that used vacuum tubes but these were clearly the exceptions. The physical structures of these electro-mechanical
38、relays were robust, with current and voltage coils designed to pass one minute power frequency production tests at 2000 volts. In addition, they were required to pass design (type) impulse tests at 5 kV. Insulation failures were rare. The most common failure modes in the field were dirty contacts, w
39、orn or dirty bearings (on induction cup or induction disc relays), or incorrect settings. Routine preventive maintenance was scheduled to address these problems. A few years after the invention of the transistor in 1948, some transistor designs became available that could withstand the typical extre
40、me temperatures in electric utility substations. Their capability as solid state amplifiers was very attractive to the designers of protective relays, as the search was always on for more sensitive and faster, yet secure, products for transmission line relaying. These products -“solid state relays”
41、(or sometimes called “static terminals”) - were often applied for EHV (345 kV, 500 kV, and 765 kV) transmission line protection to reduce fault clearing times. Relays for other functions such as transformer differential protection and automatic synchronizing also used transistors. The high voltage s
42、ubstation environment In the 1960s, the semiconductor components (e.g. transistors) in some of these solid state relays installed in the relay houses or control rooms of EHV substations were failing, and apparently not in connection with faults on a nearby EHV line or bus. As early as 1961, AIEE B15
43、, IEEE B16, and ISA B17 conference papers were published which described the transients generated in these substations when EHV disconnect switches were closed or opened. These transients, now referred to as the oscillatory SWC (surge withstand capability) transients, were found and recorded on curr
44、ent transformers (CTs), voltage transformers (VTs) and control cables in the high voltage yard. Note: It was found that switch closings create more severe transients than switch openings due to the inrush current when energizing a bus sections capacitance to ground and the capacitance of its connect
45、ed apparatus (i.e. bushings, coupling capacitor potential devices, and grading capacitors in EHV circuit breakers). In some cases, a transient ground potential rise of over 40 kV was measured in adjacent cable trenches. In a 1977 paper, “The Nature and Source of Transient Surges” B19, W. E. Kotheime
46、r wrote: “Sources of transients” “The transient surges found in protective and control circuits originate in high voltage power circuits and also in low voltage and auxiliary power and control circuits. For the purpose of this paper, these are classified simply as high voltage sources and low voltag
47、e sources.” IEEE Std 1613a-2011 IEEE Standard for Environmental and Testing Requirements for Communications Networking Devices Installed in Electric Power Substations Amendment 1: Adding of one Definition, dc power supply requirements (5.1), and Annex EHistory Copyright 2011 IEEE.

High voltage sources” “The high voltage power circuits in an electric power substation consist of all the high voltage buses and power circuits, the primary circuits of current and voltage transformers, the line-to-ground paths of all capacitor devices such as capacitor voltage transformers
49、(CVTs), carrier couplers and apparatus bushings, and include the station ground grid and all equipment grounds. They form a large cage-like structure as shown in Figure E.1 (Figure 1 of B19).” Figure E.1The high voltage structure “Note that a protective or control cable may traverse through this region which, during disturbances, can be a region of intense transient electromagnetic fields. These fields induce or couple the transient surges into
