外部電壓調(diào)節(jié)變阻器（端子R1和R2）：端子R1和R2用于連接電壓調(diào)節(jié)變阻器。
這個變阻器提供調(diào)節(jié)發(fā)電機(jī)電壓的±10%名義上的它作為面板安裝的單獨項目提供。連接變阻器的導(dǎo)線連接到端子R1和R2?？缃訉?dǎo)線必須連接在變阻器端子2和變阻器1之間如圖6所示。

電壓下降或交叉電流補償模式。按無功電壓下降或交叉電流補償。
-無功電壓降：將電流互感器連接到各自的調(diào)節(jié)器（見圖7）。
-交叉電流補償：對于交叉電流，連接每個CT至其各自的調(diào)節(jié)器。然后連接? 尼什? rst CT to第三個CT的開始等繼續(xù)，直到所有CT連接到串聯(lián)并連接? 從后一個CT結(jié)束到? rst CT

5）并聯(lián)運行的發(fā)電機(jī)需要電流互感器。連接如圖所示：1 A電流互感器和無功電壓降
補償參見圖2和圖3。
6）根據(jù)適用的電氣規(guī)范將中性點接地External voltage adjust rheostat (terminals R1 and R2): Terminals
R1 and R2 are provided for connection of the voltage adjust rheostat. The
rheostat provides adjustment of the regulated generator voltage ±10% of
nominal. It is provided as a separate item for panel mounting. Connecting
wires from the rheostat attach to terminals R1 and R2. A jumper wire
must be connected between rheostat terminal 2 and rheostat terminal 1 as
shown in Figure 6.
Connection to reactive voltage droop terminals CT?, CT1, and CT5
Parallel operation: When generators will be operating in parallel, install
the current transformer in Phase B from each generator and connect as
follows:
- Current transformer (1 A secondary): Connect secondary leads to
CT? common and CT1. Be sure to maintain correct polarity. Make
certain the jumper, when supplied, is removed from across CT? and
CT1.
- Current Transformer (5 A secondary): Connect secondary leads to
CT? common and CT5. Be sure to maintain correct polarity. Make
certain the jumper, when supplied, is removed from across CT? and
CT1.
Reactive voltage droop or cross-current compensation: The regulating
system may be connected for parallel operation in either the reactive
voltage droop or cross-current compensation mode. Connect according to
either reactive voltage droop or cross-current compensation.
- Reactive voltage droop: Connect the current transformer to the
respective regulator (see Figure 7).
- Cross-current compensation: For cross-current, connect each CT
to its respective regulator. Then connect the ? nish of the ? rst CT to
the start of the third CT, etc. Continue until all CTs are connected in
series and connect the ? nish of the last CT to the start of the ? rst CT
(see Figure 8).
- On parallel cross-current compensation applications consisting
of two or more generators, use a unit/parallel switch if all the
generators are not always on the bus. If the switch is not used,
a voltage droop will be introduced into the system, which will
cause the voltage of the incoming generator to ? uctuate prior to
paralleling. This is due to the unloaded generator parallel CT not
supplying its compensating signal, but allowing a voltage drop to
occur across it. Ideally, the switch is an auxiliary on the generator
output circuit breaker that opens when the breaker is closed.) For single-phase sensing, terminals are E1 and E3. See Figures 2 and 3.
2) The ? eld must not be opened, shorted or grounded while the generator is operating.
3) The external voltage adjust must have a jumper across its terminals 1 and 2.
4) Input power standard KCR 760 voltage is 120 Vac; optional 240 Vac. Maximum
continuous output is 65 Vdc for a 120 Vac input and 125 Vdc for a 240 Vac input. See
Figures 4 and 5.
5) A current transformer is required for generators operating in parallel. The connection is shown on this drawing: 1 A current transformer and reactive voltage droop
compensation. See Figures 2 and 3.
6) Ground the neutral in accordance with applicable electrical codes
