Grid disturbances and power quality – proving causes in the power grid via IoT measurement
Record voltage dips and power quality issues, clearly distinguish between grid and customer-side causes, and provide seamless quality verification according to EN 50160.

Precise PQ measurement
Voltage, current, harmonics, sags, swells, and short interruptions – fully recorded and accessible at any time.
Manufacturer-independent
PSsystec communicates with every energy analyzer, every protocol, and every system manufacturer – worldwide.
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
Voltage dips without measurement technology – causes remain unclear, outages recur
Short-term voltage dips ("grid blips") and power quality issues lead to system shutdowns, IT disruptions, and production downtime. Without targeted power quality measurement at the point of common coupling, it is impossible to clearly identify the cause – grid operators and facility managers argue over responsibilities while the outages continue.
- System shutdowns and production downtime due to grid blips
- No distinction between grid and customer-side causes
- Lack of quality verification according to EN 50160


The PSsystec solution
IoT power quality measurement at the point of common coupling – cellular-based, retrofittable for existing systems
The PSsystec IoT solution records all relevant power quality parameters at the defined point of common coupling – whether it is the LV output of the local substation, the MV/LV transformer output, the main distribution board (LVMDB), the industrial facility feed-in point, or a critical consumer output such as a data center or production line.
- Measurement via Modbus on certified energy analyzers from leading manufacturers
- Recording of sags, swells, THD-U/THD-I, individual harmonics, and EN 50160 evaluation
- Cellular-based data transmission, commissioning without interfering with the system
Benefits
Power quality under control – from grid blips to quality verification
Clearly verified
Document grid blips with measurement data
Voltage dips are recorded with a timestamp, amplitude, and duration – the evidence is objective and accessible at any time.
Clearly distinguished
Grid or customer-side cause – no speculation
Measurement at the point of common coupling provides objective clarity on where the fault lies – clear, documented, and verifiable.
Faster resolution
Targeted fault analysis
Comprehensive measurement data significantly accelerates root cause analysis – fewer follow-up questions, fewer on-site visits, and shorter repair times.
Standard-compliant assessment
Quality verification according to EN 50160
The recorded measurement values are automatically assessed against EN 50160 limits – providing a reliable basis for regulation, contracts, and customer communication.
Flexible application
Measurement at any point of common coupling
Whether at a local substation, industrial facility, data center, or production line – the IoT solution is installed exactly where power quality matters most.
