Data acquisition device of DVC Application of PLC in parallel and off grid switching detection of energy storage converter
Detection of parallel and off grid switching of energy storage converter
At the same time, measure the voltage at the load side and AC side of the inverter or converter, capture the action signal of the grid connection switch, and accurately test the switching time of the grid connection and disconnection.
Parallel off grid switching detection circuit
Energy storage converter parallel off grid switching Change detection Equipment:
DEWE3-A4
TRION-1810-HV-4
DEWE3-A4 portable integrated host:
Two TRION-1810-HV-4 acquisition cards can be added to collect 16 channels of voltage, or 8 channels of voltage and 8 channels of current; The range of high-voltage channel can reach ± 2000Vpeak, and the range of current channel can reach 40Apeak; Test precision: DC ± 0.02% * reading ± 0.02% * range; AC 0.5~1kHz: ± 0.03% * reading without range error; There is no gap storage, and the signal waveform can be viewed without oscilloscope.
Energy storage converter parallel off grid switching change Test content
Passive grid connection to off grid switching time detection uses AB cursor to measure the time from the time when the grid connection switch is disconnected to the time when the discharge current reaches 90% of the rated current.
