Bosch CVT upgrades EV efficiency - SAE International

WebCapacitive Voltage Transformer (CVT) is a CCVT without carrier accessories. The paper will use these terms interchangeably. Even though there is a slight difference between the two, the portion of the device in that pertains to the transient response is the same. CVT Design . Figure 1 shows cut away view of a capacitor voltage transformer. WebUsing a modified Trench 145kV, 60Hz nominal voltage TEMP138 CCVT model built with tapped (115Vrms) secondary voltage terminals and special harmonic monitoring terminals (200Vrms), a frequency scan test was performed using the test circuit shown in Fig. 1. The objective was to take advantage of the capacitor divider as an integral part of CCVT ishimoto architectural \\u0026 engineering
