Test function

(1)Load bank testing: 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) Control Mode: local, remote or intelligent control(software) for choosing.

 (3) Remote Control:through the switch in the remote control box, control the load over a long distance.

(4) Intelligent Control: through data processing software, realize all the test functions, display, record and manage the testing data, and generate curves, graphs and tables can be printed.

(5) Control Mode Interlock: with control mode switch, no matter chooses which mode, operation of other mode is invalid, avoid the clash.

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

(7) Local meter display data: local meter can display 3 phases voltage, current, active power, frequency and so on

(8) Temperature detection function: The temperature of the air outlet in resistor bin can be displayed by the local temperature measurement instrument.

(9) Auxiliary function: The control panel is designed with a lighting switch, and a 220V power socket is reserved for computer or other temporary power consumption.

Software function

(1) Communication Mode: using photoelectric isolated RS485 communication serial port connect to PC, and with great anti-interference performance to make system control stable. Through converts like USB or RS232 realize communication protocol conversion.

(2) Load Mode: manual load or automatic load

(3) Manual Load: input power and power factor, and load according to the preset value.

(4) Automatic Load: set several load stages and duration, then complete the process according this stages automatically. 0%- 25%,- 50%,- 75%, -100%

(5) Real-time Monitor: through software display main parameter value, such as voltage, current, power, power factor, frequency and time.

(6) Security monitoring and control: monitor working state of the load bank by watching software light, when abnormally stop and protect, it can show the reason.

(7) Data Collection Interval: the minimum data resolving time is 2s.

(8) Data save and query: all the test data is saved in the software, easy to query in the history testing data.

(9) Graphical display: show real-time or history testing data, and support to print curve and graph as follows:

1) Graphs of real-time voltage, current, frequency and power; 2) Voltage graph

3) Current graph; 4) Power graph; 5) Frequency graph; 6) Power factor graph

(10) Data format: all the curves and graphs can be outputted as"JPG"format, testing data can be outputted as ”Excel” format, and can be printed.

 Protection Function

(1) Short Circuit Protection: when short circuit, fuses in the load bank can insure to unload automatically.

(2)Overvoltage protection: When input voltage is over the safety value, it will unload automatically and give an alarm.

(3) Overheating Protection: temperature is over the safe threshold value, system unload automatically and give an alarm.

(4) Smoke Fog Protection: If there is smoke fog in the container, system cut off load automatically and give an alarm.

(5) Fan Delivery Protection: insufficient air volume with any fan, system unload automatically and give an alarm.

(6) Overload Protection With Fan: when any fan cannot normally work, the load bank can unload automatically and give an alarm.

(7) Emergency Stop: manually press the Emergency Stop switch on the panel, then load bank is in locked state, and cannot do any operation.

(8)Control Room Alarm:When the remote operation or intelligence operations, if operating room door is not closed, the corresponding warning light with ring.

(9) Air Outlet Alarm:the door do not open when running, light up with ring.

(10) Maintenance Room Alarm: the door do not close when running, light up with ring.

(11) Temperature On-line Monitor: Avoid load overheat, when temperature exceed setting value, will send alarm and unload automatically.

(12)Chassis Ground Protection: in order to avoid the danger of electric shock when operating, the load bank is equipped with special ground protection terminal.
