Measuring Control Function
--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.
--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.
-- Control mode: user can choose local control or intelligent control (PC control)
-- Local manual control: there is local control panel in load bank, with multi load steps, min load steps 1kW, controlled by buttons.
-- 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.
-- Control mode interlock: there is switch in control panel to choose control mode, other control mode is invalid if user choose one control mode.
--Local meter display data: Local meter can display three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, etc.
--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.
--Load Mode: steady-state load (manual load, preset load and automatic load) and transient state load ( instant load and instant unload ).
--Manual Load: input power and power factor, and load according to the preset value.
--Automatic Load: set several load stages and duration, then complete the process according this stages automatically. Pause at any time or start to next stage in the load process.
--Parallel Test: several load banks work in parallel, the parallel test via software. Parameters of each set can be displayed in each meter and total parameter values can be displayed and recorded.
--Real-time Monitor: through software display main parameter value, such as voltage, current, power, power factor, frequency and time.
--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.
--Data Collection Interval: the minimum steady-state data resolving time is 2 seconds.
--Data saving and in query: testing data could be saved in software, user can query at any time.
--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
--Data format:charts and graphs are output in format of JPG while testing data output in Excel format, and all can be printed.
--Emergency stop: you can press the Emergency Stop switch in the panel, when the load bank is locked in this state, it cannot add any load
--Overvoltage protection: when input voltage is over the safe value, it can unload automatically and give an alarm.
--Short circuit protection: when short circuit, fuses in the load bank can insure to unload automatically.
--Overheating protection: when temperature is over the safe value, it can unload automatically and give an alarm.
--Fan interlock protection: load bank cannot add any load when working power of fan is
--Overload Protection With Fan: when any fan cannot normally work, the load bank can unload automatically and give an alarm.
--Phase sequence protection of fans: When control power cable in wrong connections, 3 phase fans can also work in good conditions.
--Protection Buttons: There are buttons for some protection, when misinformation occurs or user has special needs, user can temporarily turn off the corresponding protection function.
--Chassis Ground Protection: in order to avoid the danger of electric shock when operating, the load bank is equipped with special ground protection terminal.
