Protection function
Conduct compliance check according to
factory parameters or parameters set
through the controller
This item is generally not easy to test when the
system is in the operation. It is usually conducted
when the protection function of the power supply is
abnormal due to frequent occurrence of AC or DC
protection. Test methods including testing the AC
under/overvoltage protection function through
external voltage regulator and testing the DC
under/overvoltage protection function by forced
discharge
8
Management function
The calculation, storage and battery auto-
management functions performed by the
controller. The historical alarm record can
be queried, and the battery auto-
management function is testable
1. Storage function: simulate an alarm, the controller
will record the alarm information.
2. Battery auto-management: the battery charge
mode and charge current can be adjusted and
various protections can be implemented through the
monitoring module according to the data set by the
user

Noise index
peak – peak noise ≤ 1680mV
scillograph
During noise measurement, the batteries should be
separated from the power equipment. However, for
the sake of safety of power supply, the batteries
cannot be disconnected during field operation.
Therefore, this test should only be done when the
communication quality of the exchange is poor and
the power supply quality of the power equipment is
considered not in conformity with requirements. The
psophometrically weighted noise, input through the
positive and negative busbar, can be measured by a
noise meter, which shall be geared to “telephone
noise” measurement scale. The peak – peak noise
can be measured by an oscillograph. For test method
refer to the equipment operation instructions
10
Internal connection
The socket shall be well connected; the
cables shall be well laid out and fixed;
there shall be no cables that have been
squeezed out of shaped by metal
components; and there shall be no partial
overheat or aging of connection cables
Check according to standards
11
Vent duct and dust
deposit
There shall be no blockage or dust deposit
in the vent ducts of rectifier fans or vent
ducts in the cabinets
Hairbrushes, leather
bellows, etch
Remove, clean and wash the guard boards of the vent
ducts and the fan; replace them after they have been
dried
12
DC cables
The permissible voltage drop determined
in circuit design is generally less than 0.5V
(low impedance distribution)
Note down the maximum current flowing through the
cables, look up the sectional area and wiring length of
the cable in the design plan, calculate the voltage
drop and check whether it meets the design
requirements
13
Configuration of DC
circuit breakers
The rated current of the DC circuit
breaker should not be more than twice of
the maximum load current. The rated
current of the circuit breaker in each
special equipment room should not more
than 1.5 times of the maximum load
current
Check the adaptability of the circuit breakers
according to the recorded maximum current of each
load
14
Voltage drop and
temperature rise of nodes
If below 1000A, the voltage drop should be
≤ 5mV for every hundred ampere; if above
1000A, the voltage drop should be ≤ 3mV;
and the temperature rise of node should
not exceed 70°C
Multimeter, point-
thermometer
Use multimeter to measure the voltage drop between
the buses and cables at the two terminals of the
node; and judge the rationality of the voltage drop of
the node based on the current flowing through the
node. Use the semiconductor thermometer to
measure the temperature rise of the node. The
measurement results should meet the temperature
rise limitation and voltage drop limitation
requirements
