The main findings reveal that the temperature has the most evident impact on the inductive voltage transformer performance, as well as the burden, causing significant changes in ratio error and phase displacement at the lower temperatures. As for low-power ITs, establishing a priori the effects of...
Finally, Appendix A contains the manufacturing data of the studied transformer along with the symbol descriptions. 2. Single-Phase Transformer Model with Nonlinear Characteristics of the Ferromagnetic Core We have adopted the well-recognized and widely-known Steinmetz model (Figure 1) [19] for this ...

Low-voltage <1000 V circuit breakersare represented by the first two of the following symbols shown in Figure 3. Medium-voltage circuit breakers shown on a one-line typically incorporate the Basic Square Breaker symbol with theANSI Device Number 52inside. Medium-voltage breakers may be either fix...
The device is a 100-VIN Primary-Side-Regulated (PSR) flyback DC/DC controller based on sampling the primary winding voltage of the transformer to achieve tight output regulation and high efficiency, without using the opto coupler nor tertiary bias winding like in a conventional flyback converter...
