It is more useful than a screen image because another reviewer can see what the record includes.<\/p>\n<h3 style=\"margin:28px 0 12px\">Does a command timestamp prove that a capacitor stage operated?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. A command identifies what the controller requested. Keep available feedback, alarm information, and a separately documented electrical capture so the report distinguishes requested action from observed evidence.<\/p>\n<h3 style=\"margin:28px 0 12px\">Why should APF and compound-switch records be kept separately?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">They may be reviewed together, but they answer different questions. A switching sequence is not a controlled APF performance comparison and cannot establish mitigation, compatibility, or an acceptance result on its own.<\/p>\n<h3 style=\"margin:28px 0 12px\">What harmonic information belongs with a switching log?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Retain the measurement boundary, meter setup, event window, operating state, and the circuit arrangement known at the time, including any reactor or bypass note. This lets a reviewer see whether unlike conditions are being compared.<\/p>\n<h3 style=\"margin:28px 0 12px\">Can a logged event identify the cause of resonance?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">No. It can identify an observation and preserve the conditions around it. A resonance or root-cause conclusion needs an appropriate study and project-specific electrical review.<\/p>\n<h3 style=\"margin:28px 0 12px\">What should be sent for a compound-switch product review?<\/h3>\n<p style=\"margin:0 0 16px;line-height:1.7\">Provide the one-line diagram, nominal system details, stage and APF locations, measurement setup, controller exports, event times, operating log, topology notes, protection information, installation constraints, and the proposed acceptance scope.<\/p>\n<h2 style=\"margin:42px 0 14px;scroll-margin-top:96px\" id=\"references\">R\u00e9f\u00e9rences<\/h2>\n<ul style=\"margin:0 0 18px 1.2em;line-height:1.7\">\n<li style=\"margin:0 0 8px\"><a href=\"https:\/\/ieeexplore.ieee.org\/document\/5630210\/\" rel=\"nofollow noopener\" target=\"_blank\">IEEE Xplore record for intelligent compound-switch development<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a href=\"https:\/\/www.electrical-installation.org\/enwiki\/Possible_solutions_for_power-system_harmonics\" rel=\"nofollow noopener\" target=\"_blank\">Schneider Electric guidance on harmonics and capacitor-bank configurations<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a href=\"https:\/\/standards.ieee.org\/ieee\/519\/5892\/\" rel=\"nofollow noopener\" target=\"_blank\">Aper\u00e7u de la norme de contr\u00f4le des harmoniques IEEE 519<\/a><\/li>\n<li style=\"margin:0 0 8px\"><a href=\"https:\/\/ieeexplore.ieee.org\/document\/5449147\/\" rel=\"nofollow noopener\" target=\"_blank\">IEEE Xplore record on three-phase intelligent composite-switch development<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Intermittent switching and harmonic observations become useful only when they can be traced to the same part of the electrical system.
