Transformer station monitoring and load profile tracking in the low-voltage grid

Identify distribution network bottlenecks before they occur – with IoT-based measurement at local substations, cellular-enabled, retrofit-ready, and ready for immediate operation.

Identify bottlenecks early

Load peaks and overload situations in the low-voltage grid become visible before they lead to power outages.

Base network planning on measurement data

Load profiles, capacity utilization, and power quality provide the objective basis for targeted grid expansion and the preparation of §14a EnWG measures.

Retrofit instead of new installation

Digitize existing systems – without retrofitting, without interfering with the equipment, and without any operational downtime.

Plug-and-play upon delivery

Up and running in hours. No on-site IT infrastructure required—simply plug in and get started.

Challenge & Solution

The problem

Low-voltage grids without measurement data – load peaks, bottlenecks, and voltage problems remain invisible

PV feed-in, e-mobility, and heat pumps create dynamic load peaks in the low-voltage grid. Without continuous transformer station monitoring, grid operators and municipal utilities are flying blind – without reliable data for bottleneck detection, network planning, or regulatory compliance.

Uncontrolled load peaks from PV, e-mobility, and heat pumps
No overview of capacity utilization and power quality
Lack of measurement basis for grid expansion and §14a EnWG

The PSsystec solution

IoT load profile monitoring at the local substation – cellular-enabled, retrofit-ready for existing systems

The PSsystec IoT solution measures load profiles, power quality, and capacity utilization directly at the LV output for each feeder – optionally supplemented by busbar, transformer LV side, and station room temperature for thermal assessment.

Measurement per LV output/feeder, cellular-enabled via LTE and NB-IoT
Optional: Busbar, transformer LV side, and station room temperature
Commissioning in just a few hours, without interfering with existing infrastructure

Benefits

Keep an eye on the grid – from the local substation to network planning

Early

Identify bottlenecks in the low-voltage grid

Load peaks and overload situations are recorded before they lead to power outages – no inspection trips, no on-site presence required.

Objective

Targeted grid expansion planning

Measurement data from transformer station monitoring provides a reliable basis for making economically sound grid expansion decisions – moving beyond estimates and rules of thumb.

Improved

Optimize grid operations

Continuous load profile data makes distribution grid operations transparent, responsive, and verifiable.

§14a EnWG-ready

Prepare for flexibility and load management

The measurement data infrastructure is the prerequisite for §14a EnWG-compliant control measures – implement today to ensure regulatory compliance tomorrow.
