busbarPTWire breakage alarm

Guodian Nanrui NSR689RF-D Voltage Measurement and Control DeviceSet up three sections of busbarPTThe disconnection alarm has the same protection principle. busbarPTThe disconnection alarm is judged by the decrease in line voltageAccording to the criteria, its action value, return value, and system parameters“PTThe setting of "secondary rated value" is related, and the rated value is set to100VAt that time, the line electricityPressure less than70VStart at time, greater than80VReturn in time; Set the constant value to220VWhen the line voltage is less than154VStart at time, greater than176VReturn in time; Delay after startup10sgive an alarm.

Bus grounding alarm

NSR689RF-DSet up a three section busbar grounding alarm, with the same protection principle. Zero sequence voltage when the busbar is grounded3UoValue increases, greater than40VStart up; Delay after startup10sgive an alarm.
