Low Voltage Regulation Systems (LVRSys®)

LVRSys^{^®} offer precise voltage stability in the low voltage grid and in industrial applications by adjusting highs and lows independently for each phase, enhancing phase symmetry.

Unlike expensive and time-consuming traditional line expansions in power utility grids, our LVRSys^{^®} provide a cost-effective and efficient alternative for addressing voltage fluctuation issues. Housed in a "street cabinet," it’s quasi-mobile, allowing for relocation to other grid hotspots after deployment.

A. Eberle Africa is one of the only providers of voltage stability solutions in Africa & has installed over 1 000 systems worldwide. Enquire today!

Our LVRSys^{^®} operate similarly to a regulated distribution transformer, or even better, functioning as a feeder controller deep within the grid to address voltage issues without impacting other feeders or loads.

Embrace the future with our outdoor, indoor or pole-mounted systems that offer:

Voltage stability from all power sources

Voltage control in municipal or industrial low voltage grids from 7.5 kVA up to 630 kVA

1- or 3-phase voltage regulation of each phase (voltage balancing)

Regulation ranges from ± 6% up to ± 20% of the nominal voltage

Adjustable response time of the controller < 30 ms to 100 s

Integration with customer requirements

Overall efficiency of 99.4% to 99.8%

Grid configurations of TT / TNC-C / TN-S / IT

Achieve voltage stability in your low-voltage electrical distribution systems, even during voltage fluctuations!

Why use our LVRSys^{^®}?

Our modular solutions are flexible, meaning that we can meet your customer-specific requirements.
Our systems ensure that your grid voltage meets the voltage band to comply with the NRS048-6:2019 mandate.
Our devices are proven, robust and service-friendly, solving voltage problems and reducing network losses.
Simple to operate, assemble and dismantle.
All 3 phases are controlled independently, improving the grid voltage asymmetry.
Suitable for various applications, from controllable street cabinets to the control of an entire grid area.
Our systems can generally be used for over 30 years.
Low operational costs (minimal maintenance requirements).
Maintenance is limited to cleaning the switch cabinet and checking the screw connections.
Typically, customers do not require training! Our system is as simple as flicking a switch.
Option available with power quality measurement device(s) PQI-DA smart (input and/or output side according to IEC 61000-4-30, Ed. 3, Class A).
