Portable Test Rectifier
The test rectifier consists of a medium power silicon rectifier mounted on an appropriate heat sink in a small molded case. Connections to the terminals at each end of the case may be made by clamping leads or terminal under the molded thumb nuts, or by clipping the leads directly to the hexagonal portion of the terminal. A half wave rectifier symbol is shown on the nameplate of facilitate proper choice of DC meter connections.

XTM Test Plugs and Card Extenders
Applications
The XTM test plug is available for testing modular type relays. The connection plugs can be removed from the modular relay, and the XTM test plug can be inserted for current injection testing and input/output access. The modular relays have two connection plugs and require two test plugs, one right-hand test plug and one left-hand test plug. The handle of the test plug may be pulled out and turned to the right for easy access to connection points.

XLB Test Block Panels
The XLB Test Block Panel is designed for use with GE Vernova 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 Vernova 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.

XLA Test Plugs for Drawout Relays
Applications
The test plug provides a quick and easy means of testing drawout case relays or meters without removing them from their cases. The test plug is substituted for the regular connecting plug and there is nothing to disconnect. The XLA12A enables power to be applied to the relay from either a separate source or the source that feeds the equipment. The XLA13A can only be used when a separate source of power is available.
To insure low-contact resistance the test plug contact fingers are silver plated.
