BP400 series microcomputer programmable protection and
supervision device is a digital relay protective device used for the
protection, control, measurement and supervision of 35KV and below power grid,
such as distribution line, incoming line, passing line, capacitor bank, motor,
PT and etc, suitable for different system covering: neutral point unearthed
system, the system earthed by small resistance, or earthed by arc suppressing coil.
Different ports: 7CT,4PT,10DI,7DO, to realize different connection
modes.
Precise
time calibration and communication: GPS B code time calibration supported, 2
pcs RS485 ports support dual communication networks, support MODBUS and IEC60870-5-103
protocol, it can use different protocols under different networks at same time,
to provide a high reliable network communication.
High accurate measurement: collect the electric
parameters precisely, the loops of measuring current and protective current are
independent, which can improve the protection reliability and measurement
accuracy. The accuracy to measure voltage, current and power factor reach up to
0.2 class, the accuracy of measuring the four quadrant power and KWh up to 0.5
class.
Powerful
graphic programming: complete programmable resources provided for graphic programming,
easy operation, widely applications, and protections can be designed according
to user request.
High
reliable design: all components are of industrial level, full electric
isolation is executed, completely in consideration of EMC, self-detected
function and etc, all of these ensure the device can operate durably and reliably.
Event
analysis and record: able to record 100 pieces of SOE events.
