Substation-level Automated Analysis

sub.net captures fault and disturbance recordings, and  performs analysis on-site in real-time. This analysis allows the unit to report ready classified results immediately. A remote Masterstation is not necessary – get the data in seconds on your PC or mobile!

The capture and understanding of fault events is vital to ensure the reliability and continuous operation of the power system. During a rapid series of fault events, Sub.net gathers these together with an RMS recording into a single report document. This allows easy interpretation of recloser sequences.

Long term trending analysis is also performed continuously, recording up to 26 weeks of measurements. This allows on-demand generation of trend records, which can provide insight into power system performance over periods from hours to months.

Embedded Event Analysis:

• Embedded Event Classifier – minimise engineering time
• Fault classifier – line fault identification, fault current.
• Protection monitoring – Check clearance times
• Distribution Fault Location
• Asset condition
• Voltage dips

Example protection event report

Trending:

• Voltage, current, frequency.
• Power Quality
• Flicker,
• Power measurement,
• Power factor & Imbalance.
• Sequence components

Example harmonics trend report

Wide area monitoring & analysis is supported via Phasor measurement.
