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.

MENU
) KEY on the initial screen
② Move the ‘5.POWER SYSTEM’ using the UP( ) and DOWN( ) KEY and input the RIGHT ( )Key.
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.
※ The setting category may be different for each product, so please refer to the user manual for each product for details.

▶ 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

Over current (OCR1) 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.
Over current (OCR1) element fault occurred and
the output contact operated, but the fault current

CAUTION
• In a normal case, the magnitude of voltage and current may be different, and the phase should be
displayed with a value similar to the example shown above for normal wiring.
• A phase voltage is the standard for phase display, and the magnitude of voltage/current/power indicates
the primary value to which RATIO is applied.
(In case of F10 without voltage A phase, current A phase is the phase reference)
• In the case of a directional element, since it operates with the magnitude and phase of voltage and
current, malfunction or non-operation may occur if it is not in the normal phase.
• If the measured value is out of phase, check the primary wiring and the VT, CT secondary wiring.

FAQ
⑴ Although the circuit breaker is open, UVR contact output is not operating.
- If you go to the UVR setting item, there is a BLOCK VOLT setting.
This category sets the minimum operating voltage at which UVR operates. For example, if the BLOCK VOLT setting is
0.20pu and the PICKUP setting is 0.8pu, it does not operate when the voltage is below 0.2pu and only operate at a
voltage between 0.2pu and 0.8pu.
Check the settings and change them according to the site conditions.
⑵ Does frequency measure all three-phase voltages?
- Frequency measurement is the frequency of A-phase voltage.
⑶ dF/dT(81R) test does not operate even if the applied frequency is raised or lowered a lot
- When setting dF/dT to +1.0Hz, 0.3 sec, MIN V1 : 80V, the test applied voltage and frequency are 1 ÷ 0 6 ≒ 0.016[Hz],
and the frequency changed by 0.02Hz or more per at least 1 cycle is about 20 cycles (about 0.3 sec) for voltage A.
At this time, the voltage should be at least 80V.
⑷ How can the user directly change the contact settings?
- When entering the setting category of the protection element and setting the DO1~DO4 setting category to
ENABLED, if the protection element operates, the contact set to ENABLED can be output.
⑸ When the relay is installed on the panel and tested, the measured value is displayed less than the applied
current.
- Please refer to the install/withdraw method in this user's manual.
Since the enclosure and relay are drawn out, normal measurement may not be possible if the enclosure is installed
incorrectly.
⑹ Normally during solar power generation, the measured current of the relay and the measured current
measured with a clamp meter are different.
- The digital relay measures and displays only the fundamental wave excluding the harmonic content. However, most
general clamp meters and multimeters measure values including harmonic content, which may result in different
measured values between products.
⑺ During solar power generation, the power value displayed by the relay and the power value displayed by
the inverter are different.
- Move to the menu / POWER SYSTEM category and check the VT, CT 1st and 2nd ratios to see if the settings are
different from the inverter settings.
Since the values of voltage and current applied to the product are internally calculated with the values set above and
displayed as the primary value, you must check the settings and change them when they are set to different settings.
