Installing the Enclosure
Overview
The following procedures describe the steps to install the SEL-734B
Capacitor Bank Control enclosures. Parts of the procedure vary with different
enclosure models. Please refer to the applicable section for your enclosure
model.
Grounding the Enclosure
Always follow local utility grounding practices.
SEL recommends that the control power transformer serving the SEL-734B
be on the same pole as the SEL-734B, as shown in Figure 3.1. All connections
to the SEL-734B (e.g., ac supply from power transformer) must be routed in
close proximity to, and parallel with, the ground conductor path for adequate
surge protection. The connections and the ground path should be
approximately equal in length. Primary lightning arrestors should be installed
at the capacitor and at the control power transformer. All of these measures
help reduce the possibility of equipment damage because of high voltages
from surges.
Ground the SEL-734B Capacitor Bank
Control cabinet chassis before making
any other connections to the cabinet.
