5. Function

1)      User could load any power within rated power, can test stable state three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, running time of generating set.

2)      Whether load/unload by local control panel or by PC software control, user can pre-set the power then press the master load button.

3)      Control mode: user can choose local control, remote control or intelligent control (PC control)

4)      Local manual control: there is local control panel in load bank, with multi load steps, min load steps 1kW, controlled by buttons.

5)      Remote control: With remote controller box connected to load bank by control cable.

6)      Intelligent control: user can control load bank by data processing software of PC to make automatic load/unload, display, record and manager the test data, form curve, graph and can be printed.

7)      Control mode interlock: there is switch in control panel to choose control mode, other control mode is invalid if user choose one control mode.

8)      With data processing software, could form curve of current, active power, reactive power, apparent power, power factor, frequency and can be printed.

9)      One-key load/unload: user can load or unload with one key easy to control.

10)  3 line LED multi-function meter display.

6. Data Processing Software Functions

1)      Communication type: through RS232, RS485 or USB interface.

2)      Load mode: manual load or automatic load.

3)      Manual load: input power and power factor.

4)      Automatic load: User can set several periods of power and time, and in turn of0%→25%→50%→75%→100% or 110%, etc or other preset order (33%→66%→99%) to make automatic load testing.

5)      Parallel testing: when several load banks parallel working, parameters of each load bank can be displayed and recorded, so do the final parameters of paralleling working.

6)      Real-time parameter: Current, voltage, power, power factor, frequency, time, etc could be displayed by software.

7)      Safety monitoring: User can know the working conditions of load bank through software indicating light. When in abnormal stop protection, software will indicate the reasons of stopping.

8)      Data collection interval: the min saving interval is 2 seconds.

9)      Data saving and in query: testing data could be saved in software, user can query at any time.

10)   Data display: it could display real-time data and history data; user can print voltage, current, frequency, power graphs and charts.

11)   Charts and graphs are output in format of JPG while testing data output in Excel format, and all can be printed.

7. Protection

1) User can press the emergency stop button in the panel to unload immediately when the load bank is abnormal while working.

2) Over-load: Automatic load dump and give alarm when voltage is over safety thresholds.

3) Over-heat protection: Automatic load dump and give alarm when temperature is over safety thresholds.

4) Short Circuit Protection: Fuse could avoids damage to equipment when short circuit or current overload.

5) Fan protection: Machine could not do load testing before working power of fan is on.

6) When control power cable in wrong connections, 3 phase fans can also work in good conditions.

7) Fog protection: when there is fog in load bank, load bank automatic remove load and give alarm.

8) Protection button: there are some protection buttons can be switched off when false alarm or for special requirements.
