WARNING: Disconnect primary power prior to servicing.

Today, many transformers are supplied with all of the primary terminals available so
that either a delta or WYE connection can be made. Table 2-5 shows the different line-
to-line voltages that are available with this configuration.
In summary, both symmetrical power distribution systems are satisfactory because of
their balanced impedances. Use either a closed delta or a four wire WYE system for
maximum transmitter performance. Never use an open delta system just to cut costs - it
could cost dearly in the long run.
