The procedures contained in this section can be used to verify the correct operation of the

745 Transformer Protection System LC1000-S/SP7 prior to placing it into service for the first time. These

procedures may also be used to verify the relay on a periodic basis. Although not a total

functional verification, the tests in this chapter verify the major operating points of all

features of the relays. Before commissioning the relay, users should read the installation

chapter, which provides important information about wiring, mounting, and safety

concerns. The user should also become familiar with the relay as described in the setpoints

and actual values chapters.

Test personnel must be familiar with general relay testing practices and safety precautions

to avoid personal injuries or equipment damage.

This chapter is divided into several sections, as follows:

• GENERAL: outlines safety precautions, conventions used in the test procedures.
• TEST EQUIPMENT: the test equipment required.
• GENERAL PRELIMINARY WORK
• LOGIC INPUTS AND OUTPUT RELAYS: tests all digital and analog inputs, the

analog-to-digital data acquisition system, and relay and transistor outputs.

• DISPLAY, METERING, COMMUNICATIONS, ANALOG OUTPUTS: tests all values

derived from the AC current and voltage inputs.

• PROTECTION SCHEMES: tests all features that can cause a trip, including

differential, overcurrent, over and underfrequency elements.

• AUXILIARY PROTECTION/MONITORING FUNCTIONS
• PLACING RELAY INTO SERVICE
• SETPOINT TABLES
