The XLB Test Block Panel is designed
for use with GE relays that do not have test
facilities; an example being the model of
the DLP digital distance relay without test
facilities. The Test Blocks used in this test
panel utilizes the same design features used
in the drawout type construction of GE
component relays. The standard test plugs
used in testing component relays may also
be used to test relays connected to the XLB
test panel, such as the XLA12A or
XLA13A test plugs.
Each XLB Test Block is provided with
ten points. The actual number of points
required in using the test panel is
determined by the number of circuits to be
connected. Two Test Block panels are
available. Style 1
provides two XLB Test Blocks (TB1 and
TB2) and is seven inches high, while style 2
provides four XLB Test Blocks (TB1,
TB2, TB3, and TB4) and is ten and a half
inches high. Both are designed for the
standard 19 inch rack mount.
