MMLB and MMLG or P991 14-way injection test blocks and P992/3.
The 515 Blocking and Test Module provides an effective means of trip blocking, relay isolation and testing of Multilin relays. By opening the switches and inserting test plugs, phase and residual currents from the primary CTs can be monitored. Currents can be injected into the relay from a secondary injection test set during commissioning.

APPLICATION
Type PK-2 test blocks are essentially 4-pole and 6-pole jacks, provided with molded Textolite covers that have internal plug contacts, which make a through connection when the cover is in place. The contacts in the blocks are of the line- pressure type and provide positive contact with minimum contact resistance. For all current circuits, auxiliary contacts are used which automatically short circuit the current transformer when the cover, or plug is removed.
For mounting on switchboard panels for use in conjunction with proper test equipment to facilitate the testing of ac instruments, meters and relays.
APPLICATION
Three different XCA test plugs are available to provide an easy means of testing C-case drawout relays without removing them from their cases.
The XCA11A1 is a two-position four-point test probe used in testing C-case relays. It is keyed to the barrier strips in the C-case, and can only be inserted in positions 1-2, 3-4, 5-6, etc. These terminal pairs are used for current transformer connections and trip circuit outputs in C-case relays. It cannot be inserted in positions 2-3, 4-5, etc. It has contact fingers which are electrically separate, top to bottom, and are connected to standard banana-plug receptacles on the face of the probe. This test probe is furnished with an accessory shorting plug Type 0184B5461 which may be used to short out CT inputs during relay tests.
The XCA11A2 is a pre-wired test probe for use in measuring current in the CT circuits connected to a C-case relay. It consists of a Type XCA11A1 test probe to which a jumper and six-foot long (1.8 m) ammeter leads have been added.
The XCA28A1 is a full-width 14-position 28- point test plug which provides complete flexibility in testing C-case relays. It has 28 electrically separate contact fingers connected to 14 concentric binding posts. One side of the test plug is prominently marked "Relay Side" and the other "Case Side". The test plug is keyed so that it can only be inserted in the proper manner. The "Relay Side" contact fingers are connected to the black inner binding posts and engage the relay internal connections. Test leads with either spade lugs or banana jacks may be used with these binding posts. The contact fingers on the "Case Side" are connected to the outer binding posts with red thumb nuts and engage the C-case stud connections. Removable test links are furnished with each test plug for through connection, short circuiting and external wiring,. These accessory links are identical to those supplied with the Type XLA test plug.
APPLICATION
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.
APPLICATION
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.
APPLICATION
Model No. XRT12A covers a set of relay tools contained in a flexible vinyl pouch. The set consists of 18 selected tools, of suitable variety, for the proper maintenance of General Electric relays. Individual tools are described in the brochure.
The Type XTC10A Ac test panel is designed to allow an operator to check the operation of a current differential relay (DLS). This 7-inch (four rack units high) test panel, designed to mount in a standard 19-inch rack includes a variable voltage supply, a current reactor, trip test and relay status lamps, a six position relay test switch, an XLB connection plug, and a push to trip push button.
APPLICATION
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.
The card extender provides versatility for testing plug-in modules in relay. The module to be tested can be removed from the relay, the card extender inserted in place of the module, then the module can be inserted into the card extender. This gives complete access to module card for test purposes.
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.
APPLICATION
The test rectifier is a compact, portable piece of test equipment designed for calibration testing of the second harmonic restraint feature of differential or overcurrent relays.
The RTT Desktop Test Set is the ideal tool for engineers, technicians, consultants, and integrators that use relays, power meters, and PLC's on a regular basis. With the ability to provide single phase voltage and current, drive digital inputs, and control RTD's, the RTT is the ideal tool for providing hands-on training of power system devices or testing and validating the configuration of Relays, Meters and Programmable Logic Controllers.
