LV IPR-50 Pad

Low Voltage Pad-mounted 50kVA In-line Power Regulator

The Gridco Systems Low Voltage, Single-Phase, 60 Hertz, 50 kVA In-line Power Regulator™ (IPR-50) is a new class of agile grid infrastructure that combines utility-scale power electronics, high accuracy sensors, and advanced control algorithms to provide dynamic, continuous and precise load voltage regulation, VAR compensation, harmonic cancellation, and power monitoring.

Leveraging a combined series-connected voltage-source and shunt-connected current-source power electronics architecture, these multi-function devices can be used for residential-, commercial- or utility-scale renewable integration, Volt-VAR Optimization (VVO) / Conservation Voltage Reduction (CVR) for improved energy efficiency and peak capacity management, Fault Detection, Isolation, and Restoration (FDIR) for improved system reliability, and improved power quality.

The IPR-50 is a ruggedized hardware system purpose-built for harsh outdoor environments and designed for 25-year life with no maintenance.  Available with or without a Distributed Grid Controller (DGC), the pad-mounted IPR-50 can be deployed next to the pad-mounted distribution transformer or further downstream.
