Digital Integrated Protection Relay
K-PAM 5500 Series
K-PAM 5500 is a multi-functional digital Integrated
protection relay that provides high-precision measurement
and reliable protection relay function for power supply
and distribution facilities. Various protection elements
and measuring elements can be used to protect not only
distribution feeders, but also motors, Bus, generators,
solar power, ESS, and wind power generators. In addition,
various protection functions can be performed with 28
types and 60 protection elements, and the system can
be monitored in detail using 10 supervision functions and
various recording functions. You can check the fundamental
and harmonic of the system in real time through the
measurement function, and all functions can use USB,
RS-485 and Ethernet communication to enable setting
change, logic change, check status and measurement.

How to check when the operation of the protection element (In case of fault)
① Check the Front
② Check the protection relay element status window
- Press the MENU ( ) key on the initial screen
- Use the UP ( ) and DOWN ( ) keys to move the ‘DISPLAY’ category, and then press the RIGHT ( ) Key.
- Use the UP ( ) and DOWN ( ) keys to move the ‘STATUS’ category, and then press the RIGHT ( ) Key.
- Use the UP ( ) and DOWN ( ) keys to move the ‘PROTECTIVE RELAY’ category, and when RIGHT ( ) Key
is input, the following screen is displayed.
※ Through EASYLOGIC, it is possible to set whether to maintain or reset the contact after fault recovery.
The output contact factory value is maintained even if an fault release, and the output contact is reset when the
front RESET KEY is pressed.
Fault is being held
The protection element is in operation, but the fault has reset.

not operate.
(The output contact is not operate)
TOCGR1 element fault occurred and the current
higher than the set value is maintained, so the
protection element is in operation and the
output contact is in operation.
TOCGR1 element fault occurred and the
output contact operated, but the fault current
disappeared.
