Anti-islanding relay SPI1021
Product Description
Victron Energy’s Anti-Islanding Relay SPI1021 can be used to monitor the voltage and frequency in plants for own generation of electricity. It fulfills the requirements of CEI 0-21.3 selectable programs allow measuring 3 phases to neutral (4-wire mode), 3 phases phase-phase (3-wire mode) and single phase to neutral (2-wire).
The SPI1021 can monitor all de-centralized power, photovoltaic, wind or thermal plants, that feed in the low voltage and medium voltage grid. In applications with possible asymmetry >6 kVA, power balance has to be monitored extra. With the integrated certified self-test, the device can be used in plants < 6kVA.All limits are preset according to CEI 0-21.
They can be changed if required and be protected with a code and/or a seal. A counter for alarms and standbys stores the last 100 events with reason and elapsed time. In addition, the time the SPI1021 has interrupted the plant is recorded.
All values can be displayed at the device and give the operator valuable information about the availability of the plant. When the device has been installed, a self-test starts automatically. The self-test can be re-peated when required.
All values of the test are stored and can be read out at the display.
- Monitoring of under- and overvoltage 15-520 V
- Measuring of 3 phase with or without neutral or single phase
- Monitoring of over- and underfrequency 45-65 Hz
