I discovered relating to this effect inside a manufacturing facility wherever we essentially applied pure sine wave variable frequency motor controllers on lengthy cables simply because an excessive amount distortion on a lengthy cable could burn up a motor.

all courses and interfaces inside the superclass hierarchy (e.g. see Java class is current in classpath but startup fails with Mistake: Could not locate or load major course)

This has become common even in The most cost effective UPSes as it requires advantage of parts now incorporated. The key fifty/sixty Hz transformer made use of to convert among line voltage and battery voltage requirements to provide two a little bit unique turns ratios: One particular to transform the battery output voltage (commonly a a number of of 12 V) to line voltage, in addition to a next one particular to transform the line voltage to a rather increased battery charging voltage (such as a many of fourteen V).
