Digital Integrated Protection Relay
K-PAM 10 Series
K-PAM 10 Series 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, busses, generators, solar power, ESS, and
wind power generators. In addition, among 6 types
of relays, the user can select a suitable relay for the
need. You can check the fundamental and harmonic
of the system in real time through the measurement
function, and all functions can use USB and RS-485
communication to change settings, change control,
check status and measurement.

CB Control Method
① When controlling in the field, set the control authority to LOCAL.
② If you press the CB control button
OPEN
or
CLOSE
KEY in the LOCAL state, it is converted to the window to select
whether to open/close, press the ENTER key to activate the CB control, and press the ESC key to cancel the CB
control.
③ If the CB status has not changed, the CB change failure screen appears.
④ If the relay control authority is REMOTE or control is not possible due to the condition of the CB, the CB control
impossible screen appears.
If you want to control the CB remotely, the relay control authority must be set to Remote and the CB can be
controlled through RS-485 communication.

▶ DPR Setting Example
- Generally, about 20% of the generated electricity is applied.
- When the power generation capacity is 100kW, EVT 380V / 190V, CT 1000/5A
Power generation capacity ÷ VT ratio ÷ CT ratio × 0.2 ⇒ 100kW ÷ 2 ÷ 200 × 0.2 = 50W
1pu: 190V × 5A = 950W, 50W ÷ 950W ≒ 0.05pu
