Get Solar Interface Protection Units from
dependable brand ZIEHL – Germany for Gridand Plant Protection according to CEI 0-21 DEWA -standards (Approved by DEWA, Dubai, UAE), with integrated Vector Shift-Relay.
6 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 moni-tored extra.
With the integrated certified self test, the device can be used in plants < 6kVA. In programs 1-3 (3= default), the limits are preset according to CEI 0-21. In programs 4-6 they are preset according to DEWA- standard. 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 ad-dition 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 repeated when required. All values of the test are stored and can be read out at the display.
