In de afbeelding hiernaast wordt het verloop van de netfrequentie en de afwijking daarvan over 48 uur weergegeven voor sommige regelzones, die allemaal rond de nominale waarde van 50 Hz schommelen. In het West- en Centraal-Europese netwerksysteem (UCTE) treden de kleinste afwijkingen op. Vaak zijn echter de afgelopen jaren frequentieverschuivingen waargenomen als gevolg van handel op de beurs, wanneer centrales de nieuwe vermogenswaarde bij elke uurwisseling beëindigen en niet langer continu het uitgangsvermogen van de belasting van de besturingszone aanpassen tijdens de vervolgbewerking. </p><p>In het Europese netwerksysteem worden frequentiefouten op de lange termijn gecompenseerd met behulp van een kwadratuurregeling, zodat de afwijking nooit groter is dan 1000 perioden. </p> <div class="mw-heading mw-heading2"><h2 id="Afwijkingen">Afwijkingen</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Spanningskwaliteit&veaction=edit&section=5" title="Bewerk dit kopje: Afwijkingen" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Spanningskwaliteit&action=edit&section=5" title="De broncode bewerken van de sectie: Afwijkingen"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Afwijkingen in spanningskwaliteit kunnen zich uiten in de volgende kenmerken: </p> <ul><li>Een <a href="/wiki/Stroompiek" title="Stroompiek">stroompiek</a>, ontstaat bij het inschakelen van een groot vermogen</li> <li>Een dip is het tegenovergestelde; het kwadratisch gemiddelde voltage is lager</li> <li>Snelle spanningswisselingen die zich uiten in korte flitsen van het lichtniveau, ook wel 'flikker' genoemd</li> <li>Harmonische vervorming, wanneer de golfvorm van 50 hertz vervormt</li> <li>Frequentiewisselingen, wanneer de wisselspanning hoger of lager dan 50 hertz ligt</li></ul> <div class="mw-heading mw-heading2"><h2 id="Noodstroomvoeding">Noodstroomvoeding</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Spanningskwaliteit&veaction=edit&section=6" title="Bewerk dit kopje: Noodstroomvoeding" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Spanningskwaliteit&action=edit&section=6" title="De broncode bewerken van de sectie: Noodstroomvoeding"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Een <a href="/wiki/Noodstroomvoeding" title="Noodstroomvoeding">noodstroomvoeding</a> kan de spanningskwaliteit verbeteren.
