Product description

Voltage- and Frequency-Relay UFR1001E Grid- and Plant Protection according to VDE-AR-N 4105:2018-11, vde-ar-n 4110 and grid codes G59/3 + G83/2 with integrated Vector-Step-Relay The UFR1001E from ZIEHL industrie-elektronik monitors voltage and frequency in plants for own generation of electricity. It fulfills the requirements of VDE-AR-N 4105 and bdew for Germany, ÖVE/ÖNORM for Austria, G59/3 and G83/2 for UK and DIB V VDE 0126-1-1 for many countries in Europe with supplements VFR2013/2014 for France. The UFR1001E is a dual-channel device and thus one-fault-proof. Input-circuit, A/D-converter, processor and output-relay are doubly present. The processors control each other. The function of the output-relays and of the connected switches can be monitored with feed-back contacts. At an alarm the devices switches off and the reason is displayed with LEDs and signaled with transistor-outputs. The limits are pre-set according to VDE-AR-N 4105. They can be changed if required and be protected with a code and/or a seal. An alarm-counter stores the last 100 alarms with reason and elapsed time. In addition the time the UFR1001E has interrupted the plant is recorded. All values can be read-out with the integrated display and give the operator valuable information about the availability of the plant. With a test-button the function of the connected switches can be tested and their switching-time can be measured. The simulation displays the complete switching-time of device plus connected switches. When feeding into medium voltage, limit, hysteresis, alarm-delay and switch-back-delay can be individually set for U>>, U>, U, F
