Audited Supplier 2.1 Measuring Function
Steady-state Test: load power in rated range, measure generator steady-state 3 phase voltage, current, active power, reactive power, apparent power, power factor, frequency, and running time.
2.2 Dummy Load Function
2.2 Control Mode
(1) Control Mode: local, remote or intelligent control(software) for choosing.
(2) Local Control: local control panel with several power steps, load or unload by switch on-off and read parameter values from measuring meter.
(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.
2.3 Intelligent Load 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: steady-state load (manual load, preset load and automatic load) and transient state load (instant load and instant unload).
(3) Manual Load: input power and power factor, and load according to the preset value.
(4) Preset Load: input generator related parameters, then choose the preset proportion from 0% 25%, 50%, 75%, 100% or other available order and calculate the power value automatically and realize rapid load.
(5) 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.
(6) 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.
