369-LO-0-M-F-E-0-0繼電保護(hù)器
1：將直流電壓表連接到控制端子11（-）和13（+），以測量負(fù)載信號。
2.啟動原動機(jī)。發(fā)電機(jī)在等時運(yùn)行模式且不并聯(lián)，將發(fā)電機(jī)加載至盡可能接近滿負(fù)荷可能的測量負(fù)載信號電壓。
3.卸下并關(guān)閉原動機(jī)。從端子上斷開導(dǎo)線
5，并將A相CT的兩根導(dǎo)線連接到端子4。
4.啟動原動機(jī)，施加全負(fù)荷（或步驟中獲得的相同負(fù)荷2） 再次測量端子11和13處的負(fù)載信號。如果負(fù)載信號電壓不低于步驟2中獲得的讀數(shù)的1/3，則相位不正確。卸載并關(guān)閉原動機(jī)。重新連接從端子4到端子5的A相CT導(dǎo)線，保持原始狀態(tài)極性
如果相位不正確，則繼續(xù)執(zhí)行相位校正程序。如果相位顯示正確，則跳過相位校正程序并繼續(xù)至負(fù)載增益調(diào)整程序。
如果在完成負(fù)載增益和降速調(diào)整后控制負(fù)載對功率因數(shù)的變化極為敏感并聯(lián)運(yùn)行時，完成相位校正程序相位校正程序該程序要求最小功率因數(shù)為0.9。如果0.9無法獲得功率因數(shù)，通過布線追蹤是校正電流互感器相位的唯一方法。
當(dāng)CT正確匹配時，將獲得最高正電壓以相位和極性連接到負(fù)載傳感器端子。
以下程序：將確保電流互感器的正確連接。只有在以下情況下才需要：相位檢查表明相位不正確，或負(fù)載穩(wěn)定性非常差對功率因數(shù)敏感。
第一個CT與所有三個負(fù)載傳感器輸入端的試連接，極化通過（總共六個連接）。記錄負(fù)載信號電壓對于每個連接，然后將第一個CT連接到以下端子：產(chǎn)生最高正電壓，且極性產(chǎn)生最高正電壓。
在其余兩個CT輸入端子中的每個端子上嘗試第二個CT極性和記錄的電壓。然后將第二個CT連接到產(chǎn)生（且極性產(chǎn)生）最高正極的端子電壓然后在剩余的輸入端子上嘗試最后的CT，并記錄電壓。按產(chǎn)生的極性連接最后一個CT最高電壓完成程序。
Connect a dc voltmeter to control terminals 11 (–) and 13 (+) to measure the
load signal.
2. Start the prime mover. With the generator operating in the isochronous
mode and not paralleled, load the generator to as near to full load as
possible. Measure the load-signal voltage.
3. Unload and shut down the prime mover. Disconnect the wire from terminal
5, and connect both wires from phase A CT to terminal 4.
4. Start the prime mover, apply full load (or the same load as obtained in step
2) and again measure the load signal at terminals 11 and 13. If the load
signal voltage is not 1/3 lower than the reading obtained in step 2, the
phasing is incorrect. Unload and shut down the prime mover. Reconnect
phase A CT wire from terminal 4 to terminal 5, maintaining the original
polarity.
If the phasing is incorrect, proceed to the Phase Correction Procedure.
If the phasing appears correct, skip the Phase Correction Procedure and go
to the Load Gain Adjustment procedure.
If after completing the LOAD GAIN and DROOP adjustments, the
control loading is extremely sensitive to changes in the power factor
when operating in parallel, complete the Phase Correction
Procedure.
Phase Correction Procedure
This procedure requires a minimum power factor of 0.9. If a 0.9
power factor cannot be obtained, tracing through the wiring is the
only means of correcting the current-transformer phasing.
The highest positive voltage will be obtained when the CTs are correctly matched
to the load-sensor terminals in both phase and polarity. The following procedure
will assure the correct connection of the current transformers. It is required only if
the phasing check indicates incorrect phasing, or loading stability is extremely
sensitive to the power factor.
Trial connections of the first CT to all three load-sensor inputs, polarized both
ways, are made (a total of six connections). The load-signal voltage is recorded
for each connection and the first CT is then connected to the terminals that
produce the highest positive voltage, and with the polarity that produces the
highest positive voltage.
The second CT is tried on each of the remaining two CT input terminals, in each
polarity, and the voltage recorded. The second CT is then connected to the
terminals that produce (and with the polarity that produces) the highest positive
voltage.
The last CT is then tried on the remaining input terminals, polarized both ways,
and the voltage recorded. Connecting the last CT in the polarity that produces
the highest voltage completes the procedure.
