A.1 ELLIPSE

An ellipse is a curve generated by a point moving so that the sum of the distances from the two fixed points ( F 1 and F 2) called foci is a constant. The basic equation for the ellipse is

(A.1)

where X = value of the curve in one direction

Y = value of the curve in other direction

a = 1/2 major axis

b = 1/2 minor axis

We note that the foci of the ellipse F 1 and F 2 are a distance a from the ends of the minor axis. Also the major axis equals 2 a in length. For construction of the ellipse the reader is referred to Sec. 2.3.

Products & Services
Current Sense Transformers
Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications.
Telecom Transformers
Telecom transformers are used in applications which require high bandwidths and fast switching speeds. They isolate the signal between primary and secondary grounds. This product area includes DSL, xDSL, T1, E1, ISDN, LAN, WAN, Ethernet, ATM and modem transformers.
Hipot Testers
Hipot testers are electrical safety test devices that perform a variety of electrical compliance tests.
Current Leakage Testers
Current leakage testers measure the amount of current that leaks to ground.
