Definition from
NEMA Surge Protection Institute:
A negative or positive change in the wave-shape that repeats cycle to cycle, caused by light peak currents of variable-speed drives or other phase loads.
Example sentences:
Eliminating voltage notching requires that the source of the notching (commutation) be isolated or buffered from other sensitive equipment using the same distribution system. (Rockwell Automation)
The types of equipment that frequently utilize SCR control schemes and thus experience notching include DC motor speed controls and induction heating equipment. (MTE)
The notching is a normal characteristic of a phase-controlled rectifier but this paper illustrates problems that can occur on systems with low short circuit levels where the voltage notching can excite the natural frequency of the distribution system and cause significant distortion in the supply voltage.

kritumi un lēcieni
Definition from
own experience or research:
Galvenie traucējumi tīkla barošanā:<br />- pilnīgs sprieguma zudums tīklā (avārija tīklā);<br />- ilglaicīgi un īslaicīgi sprieguma kritumi un lēcieni;<br />- augstvoltu impulsu traucējumi;<br />- augstfrekvences trokšņi;<br />- frekvences novirzes ārpus pieļaujamo vērtību robežām.
Example sentences:
Lai no maiņstrāvas elektrotīkla darbināmo izstrādājumu pasargātu no strāvas avota sprieguma pēkšņa lēciena vai krituma, lietojiet sprieguma stabilizatoru, ierīci aizsardzībai pret strāvas traucējumiem vai nepārtrauktās barošanas avotu (UPS). (Izstrādājuma lietošana un apiešanās)
