Precision Energy Intelligence
Three-phase metering for power quality, supply reliability, and energy management, installed in distribution boxes, on transformers, or non-invasively on industrial machines.
Electra EMS300
A purpose-built, three-phase smart energy meter with integrated split-core CT clamps. Installs directly in distribution boxes, on transformers, or non-invasively on industrial machines, streaming high-resolution power data to the Electra cloud.

THE PROBLEM
Bad power doesn't announce itself. A transformer ages a year in a month. Tenants dispute bills no one can verify. An outage clears and no one can prove how long it lasted. From utility feeders to estates and factory floors, most operators don't measure their power, they pay for it, in shortened asset life, disputed revenue, and incidents that get blamed on everything but the wire.
See what conventional meters miss
Voltage sags, brownouts, and harmonic distortion leave no trace on standard billing meters. The EMS300 logs every event from the 2nd to the 31st order; so the first time you hear about a transient isn't from a damaged motor.
Outage timing you can prove
Every outage and restoration is timestamped on-device, even when the network is down. Compute SAIFI/SAIDI from real data — not estimates — and settle disputes with regulators, operators, or tenants on evidence.
Decisions on data, not assumptions
Visibility into events. Evidence on timing. Together, they become the layer your operations run on. Every EMS300 computes power quality and reliability metrics on-device and feeds a single Electra dashboard, so the same data you used to detect a sag is the data you use to schedule the maintenance, settle the dispute, or rebalance the feeder.
