Low Voltage Regulation Systme LVRSysTM

Outdoor

The low-voltage regulation system LVRSys™ is a cost-effective alternative to a network extension. This flexible voltage stability solution for network operators and industrial networks pays off when deployed in any low-voltage networks which have sufficient short-circuit capacity but where voltage stability is a problem.

Product overview A. Eberle

A flexible and robust system

From years of experience, we know that developed systems have to be robust and flexible. Unlike with a regulated local grid transformer, only those parts are designed to be regulated which are affected by voltage stability problems. The distribution grid is supplemented flexibly and according to need. A smart grid doesn’t just have to be smart, it also has to be resilient. The system is short-circuit-proof to 50 kA, shows great stability in the face of overloads, direct and indirect lightning strikes and is overload-resistant like an NH fuse.

Network compatible, easy to install

The system has no effect on the network, meaning it neither causes flickers nor harmonics. It ensures voltages are kept symmetrical through phase-independent regulation and can be integrated into any existing fuse design. It also guarantees an uninterruptible voltage supply.

Simple installation, intuitive and safe

To make the application of the low-voltage regulation system as intuitive as possible, its installation has been designed to be analogous to that of the cable distribution cabinet. Unlike a standard network regulator, the system can be connected in the usual way via vertical fuse rails. Safety is paramount for us. The system is fully enclosed, guaranteeing the lowest possible risk of contact.

A reliable and economical system all round

The system electronics are protected against damp in the internal regulator cabinet, fitted out to class IP66. This control cabinet is impressively efficient, for example, allowing passive cooling even in direct sunlight, making operating temperatures between -40°C and +50°C unproblematic.

Flexible, rapid and easy to use

The reaction time of the regulator can be set between <30 ms and 100 s with the regulatory algorithms adjusted to the most varied fields of application. In addition, the recorded data can be exported to a USB stick and firmware updates achieved by the same medium or by remote maintenance. Naturally, the system also provides the common communications interfaces Modbus TCP and IEC 60870-5-104.
