Current Transformers (CTs)
Six standard CTs are available for 600 volt (or less) systems. The CTs should be mounted as close to the
generator output terminals as practical and before any load devices such as power transformers and
circuit breakers. Table 2 lists the available CTs and their corresponding ratios and short-circuit line-
current ratings. Mounting and drilling dimensions for each of the six CTs are provided in Figures 4 through
9. For applications with system voltages higher than 600 volts, contact Basler Electric.
