Physical power meets digital intelligence

The power system comes first. The intelligence is built around it.

Apex Power Distribution engineers, integrates and modernizes low- and medium-voltage distribution equipment — then adds the protection, automation, communications and analytics that let the people responsible for it see what it is doing and act before something fails.

01

Physical power equipment

LV switchboards and power switchgear, MV metal-clad and metal-enclosed switchgear, automatic transfer switches, main-tie-main and paralleling — engineered, integrated and modernized with ratings and coordination that stand up to the study.

LV and MV systems
02

Protection, automation and controls

Relays, trip units, PLC/RTU logic, transfer schemes and SCADA integration over Modbus, DNP3 and IEC 61850 — documented in a control narrative and proven in factory and site acceptance tests.

Automation & controls
03

Data and machine intelligence

Combine breaker, relay, meter and sensor data to identify abnormal equipment behavior before it becomes an outage. Health scores and anomaly detection support maintenance decisions; protection keeps protecting.

AI & analytics

Device panel

Select a breaker, bus, transformer or source on the one-line. Switch layers to see how the same device appears in protection, controls, communications, sensors, data and analytics.

Automation & controls

Six layers, one architecture

Power, protection, control, communications, data and intelligence — each layer does one job, and each depends only on the layers below it. Protection never waits for the network; analytics never operate a breaker.

Power layer

The equipment that carries and switches current. Everything above exists to protect, operate and understand this layer.

Machine intelligence for power systems

Asset health you can defend in a maintenance meeting

Predictive maintenance, thermal anomaly detection, power-quality intelligence and asset health scoring — built from inspection data, operating history, sensors, alarms and maintenance records.

Asset health — 52-LM1 LV Main 1

87/ 100
Healthy

Healthy — Monitor breaker operating time trend

The score combines weighted evidence from six sources. It is a prioritization aid for the maintenance planner — it does not change protection settings or operate equipment.

Contributing factors (illustrative)

  • Inspection dataLast NETA-style inspection 14 months ago; no findings18/20
  • Operating history2,118 operations; 3 fault interruptions lifetime17/20
  • Sensor dataStab temperature ΔT normal; opening time 38 ms (baseline 32 ms)20/25
  • Alarms0 alarms / 30 days; 1 advisory (timing trend)9/10
  • MaintenanceLubrication overdue by 4 months per time-based plan12/15
  • Equipment age9 years in service (design life 30+)11/10

Weights and scoring are configured per asset class and site. Confidence is reported alongside the score when the data record is thin.

Machine-learning analytics support engineering and maintenance decisions. Protective functions and switching operations remain governed by approved protection, control and safety procedures.

The four applications

Multi-platform power expertise

Engineering and integration experience across ABB, Eaton and Schneider Electric power platforms

Multi-platform expertise for leading LV and MV switchgear ecosystems — and the monitoring layer that ties them together.

Schneider Electric / Square D

Platform experience — engineering and integration

LV switchboards and LV power switchgear, MV metal-clad and metal-enclosed switchgear, trip units and protective relays, power meters

Eaton

Platform experience — engineering and integration

LV switchboards and LV power switchgear, MV metal-clad switchgear and vacuum breakers, trip units and relays, power monitoring

ABB

Platform experience — engineering and integration

MV metal-clad switchgear and vacuum breakers, protective relays and IEDs, LV power breakers and switchgear, condition monitoring

Capabilities across platforms

  • · Equipment integration
  • · Modernization and retrofit
  • · Breaker applications and replacement planning
  • · Metering and power quality
  • · Protection settings coordination
  • · Controls and transfer logic
  • · Communications and SCADA integration
  • · Field support, testing and commissioning

Most facilities run more than one manufacturer's equipment. Engineering and integration experience across ABB, Eaton and Schneider Electric power platforms lets us specify, coordinate and modernize what is already installed, connect it to a common monitoring layer, and plan replacements on the customer's schedule rather than a single vendor's catalog.

    Switchboard vs. Switchgear: What Actually Differs

    Switchboards and low-voltage power switchgear both distribute power at 600 V and below, but they are built to different standards and behave differently under fault, during maintenance and across a service life. This article lays out the concrete differences and the conditions under which each is the right specification.

    Metal-Clad vs. Metal-Enclosed MV Switchgear

    Metal-clad and metal-enclosed are not synonyms: metal-clad is a specific class of medium-voltage switchgear with construction requirements that metal-enclosed interrupter switchgear does not have to meet. Understanding the difference keeps specifications honest and prevents paying for, or missing, features the application needs.

    Main-Tie-Main Systems: Design and Automatic Transfer Logic

    A main-tie-main lineup splits the bus so that two sources each carry part of the load and either can pick up the whole load when the other is lost. The value is in the automatic transfer logic, and this article explains how source loss is detected, how the transfer is sequenced, and which interlocks keep the scheme from doing harm.

    Predictive Maintenance for Switchgear and Breakers

    Predictive maintenance uses operating data and trends to schedule breaker and switchgear work when the equipment needs it, rather than on a fixed calendar. This article explains how it differs from time-based and condition-based programs, which failure modes it can realistically anticipate, and where human judgment stays in the loop.

    What Is Digital Switchgear?

    Digital switchgear is conventional low- or medium-voltage switchgear in which sensors, intelligent electronic devices (IEDs) and communications are designed in as part of the assembly rather than added as accessories. This article defines the term, explains what changes inside the lineup, and weighs the benefits against the practical caveats of adopting it.

    Cybersecurity for Digital Switchgear and Power SCADA

    Once relays, meters and controllers are networked, the switchgear lineup is part of the facility's attack surface. This article covers the concepts that matter for protecting power distribution systems, from network segmentation and access control to device hardening, logging and the standards that define what secure IEDs and secure architectures look like.
