Insul Mode
No/Res
Res
Perform insulation management when ‘Res’ is selected, and no insulation management when ‘No’ is
selected (this parameter will only be displayed when HDU is set as the Master)
Insul Thres
0.5 ~ 50K
28K
When the resistance of positive or negative bus to ground is less than this limit, the insulation fault
alarm will be issued
Volt Limit
10 ~ 200V
60V
When the difference between voltage of positive to ground and negative to ground is bigger than
this limit, insulation resistance imbalance alarm will be issued, and resistance will be switched to
calculate the resistance of positive or negative bus to ground
Dschg Delay
0.5 ~ 30s
20s
In insulation management, the time for voltage to become stable after resistor is cut-in
Cut Inter
10 ~ 18000s
3600s
In insulation management, the time interval between detections
Branch Adj
Y, N
N
Whether to control the EGU to calibrate the current transformer
BrhTest Delay
5 ~60s
20s
In case of insulation failure, the time to be waited for branch circuit inspection after resistor is cut-in
BrhDschg Delay
1 ~ 30s
10s
In case of insulation failure, after resistor is cut-in in main circuit, the time for bus voltage to become
stable
BusVoltStable
0.1 ~ 10V
0.7V
When the difference between the voltages of positive or negative bus to ground measured two
times is less than this value, we consider the bus voltage has become stable
