Electrical Equipment Testing list and Electrical System Tests

Field checks and tests shall be according to NETA-ATS. Such tests shall include, but not be limited to the following:
a. Visual check of wire and cable connections.
b. Check ac and dc control circuits for short circuits and extraneous grounds.
c. Check phase rotation of switchgear and motor control centers.
d. Check equipment for proper mechanical adjustment and freedom of operation.
e. Motor run-in.
f. Function tests of power, control and lighting circuits.
g. Function tests of electrical signal and alarm systems.
h. Continuity check of low voltage power and control circuits.
i. Insulation resistance, continuity, and dc high potential tests on medium and high voltage cable.
j. Check resistance of grounding system.
k. Check polarity of current transformers and potential transformers.
l. Check current transformer ratios and continuity of the secondary circuit.
m. Function tests shall be performed on the following major equipment:
(i) power and distribution transformers
(ii) medium voltage switchgear and circuit breakers
(iii) medium voltage motor controllers
(iv) low voltage switchgear and circuit breakers
(v) low voltage motor control centers
(vi) uninterruptible power supplies and other types of battery and charger systems
(vii) motors
n. Function tests, to determine proper operation, shall be performed on all components, for example switches, circuit breakers, relays, and starters including control interlocks and sequential control circuits.
o. Special tests recommended by the manufacturer.
