SPS2 Circuit Breaker (15kV-245kV)
... The distinguishing feature of dead-tank technology is that the interrupter chamber is accommodated in an earthed metal housing. With this arrangement, the SF6 gas filling insulates the high voltage live parts of the contact assembly from the housing. The connection to the high voltage is via a SF6 o ...

1. Introduction
... Both phasor plots and magnitude bar charts are given. It is important to note that if a transformer is connected grounded-wye:grounded-wye or delta:delta, then the voltage sag on the low-voltage side of the transformer is the same as on the high-voltage side, as illustrated in Figure 5 for the singl ...

IF YOUR DOORBELL DOESN`T RING
... It’s annoying when a doorbell doesn't work! But you can do more than hang up a “Doorbell out of order” sign. In most cases, broken doorbells are pretty easy to diagnose and cure. Most often the problem is in the doorbell switch. To check this possibility, you simply unscrew the doorbell button to ge ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
