為DECS-100提供B相發電機線路電流的變壓器（CT）。此值（1或5）
對于固件版本低于1.12.01的裝置，必須手動輸入版本號。這兩個只讀版本號表示BESTCOMS軟件版本和DECS-100嵌入式軟件版本。版本號僅在通信時顯示
在DECS-100和BESTCOMS之間建立。
樣式號。三個只讀樣式編號字段表示電氣特性和DECS-100的操作特征。只有在以下情況下通信時，才會顯示樣式號：建立了DECS-100和BESTCOMS。
發電機PT比。發電機感應變壓器的比率輸入該設置字段。這比率允許通過BESTCOMS顯示的電壓與實際發電機輸出電壓相匹配。A.可以以0.01的增量輸入1比150的比率。
發電機CT比率。發電機B相電流互感器的比率輸入該設置字段。
該比率允許DECS-100顯示的電流與實際B相發電機輸出相匹配現在的可以以0.1的增量輸入1到3000的比率。
母線電壓比。該設置字段用于輸入母線電位傳感變壓器比。這個比率允許通過BESTCOMS顯示總線電壓。可以在0.01中輸入1比150的比率增量。
SETTING DEFINITIONS
Each of the six setting groups has a corresponding BESTCOMS screen. The settings of each screen are categorized by one or more tabs. In the following paragraphs, settings are arranged and defined
according to the organization of the BESTCOMS screens and tabs.
System Configuration
The System Configuration screen consists of one tab labeled System Settings. Click the Configure
button to access the System Configuration screen or click Screens on the menu bar and click System Configuration.
System Settings
System settings are shown in Figure 5-6 and described in the following paragraphs.
Sensing Voltage. This setting is used to configure the DECS-100 for either single-phase or three-phase sensing voltage.
Limiter Mode. This setting enables and disables the excitation limiters. Overexcitation limiting (OEL) or underexcitation limiting (UEL) can be enabled independently, both can be enabled, or neither limiter enabled. OEL Type. This setting configures the overexcitation limiter as a summing point limiter or takeover-style limiter.
Generator Frequency. This setting is used to select a nominal system operating frequency of 50 hertz or 60 hertz.
Regulator Sensing Voltage (V). The nominal, ac generator voltage obtained from the generator sensing
transformer is entered in this setting field. Voltages within the ranges of 100 to 140 Vac, 200 to 280 Vac,
or 400 to 560 Vac may be entered in 0.1 Vac increments. A setting of 600 Vac is also possible.
Regulator Sensing Current (A). This setting field reads and displays the nominal output of the current
transformer (CT) that supplies the DECS-100 with B-phase generator line current. This value (1 or 5)
must be manually entered for units with a firmware version lower than 1.12.01. Version Numbers. These two read-only version numbers indicate the BESTCOMS software version and
the DECS-100 embedded software version. Version numbers are displayed only when communication
between the DECS-100 and BESTCOMS is established.
Style Number. The three, read-only style number fields indicate the electrical characteristics and
operational features of the DECS-100. the style number is displayed only when communication between
the DECS-100 and BESTCOMS is established.
Generator PT Ratio. The ratio of the generator sensing transformer is entered in this setting field. This
ratio allows the voltage displayed through BESTCOMS to match the actual generator output voltage. A
ratio of 1 to 150 may be entered in increments of 0.01.
Generator CT Ratio. The ratio of the generator B-phase current transformer is entered in this setting field.
This ratio allows the current displayed by the DECS-100 to match the actual B-phase generator output current. A ratio of 1 to 3,000 may be entered in increments of 0.1.
Bus PT Ratio. This setting field is used to enter the bus potential sensing transformer ratio. This ratio allows the bus voltage to be displayed through BESTCOMS. A ratio of 1 to 150 may be entered in 0.01 increments.
