About Switchgear Monitoring

Switchgear Monitoring System

Switchgear controls, protects, and isolates electrical equipment — ensuring safe distribution and fault detection to maintain power system stability. Found in substations and industrial setups, it includes circuit breakers, fuses, isolators, and relays designed to handle various voltage levels and ensure safe operations.

MonitEasy's IoT-based switchgear monitoring continuously tracks all critical parameters — from cable compartment temperatures and humidity to THD, oil levels, and energy metering — helping your maintenance team detect degradation before it leads to a failure.

Root Cause Analysis

Why Switchgear Fails

Understanding failure modes is the first step to prevention. SGMS monitors every parameter linked to these failure causes — supporting earlier intervention before costly outages.

Insulation Degradation

Aging insulation causes short circuits and failures. Cable compartment temperature monitoring detects thermal stress on insulation before breakdown.

Corrosion

Moisture and chemicals corrode parts, leading to faults. Humidity sensors in the cabinet detect moisture ingress before corrosion develops.

Overloading

Exceeding capacity stresses components, causing breakdowns. Real-time current and kVAh tracking with threshold alerts help flag sustained overload conditions.

Mechanical Wear

Frequent use wears out critical parts. Thermal anomaly trends can indicate developing mechanical issues ahead of visible signs.

Poor Maintenance

Lack of upkeep results in undetected issues. Continuous monitoring and auto-generated reports support timely, data-driven interventions.

Aging Equipment

Old or improperly installed equipment fails more often. Historical trend data helps flag assets approaching end-of-life.

Key Parameters We Monitor

8 Critical Switchgear Parameters

SGMS helps prevent switchgear failures by continuously tracking key operational and environmental parameters, allowing early detection and optimised performance.

1
Basic Parameters (V, I, PF)
Voltage, Current, and Power Factor across all phases — core electrical health indicators for every switchgear unit.
2
Energy Parameters
kWh, kVAh, kVARh — track total energy consumed, apparent power, and reactive power over time.
3
THD for Current & Voltage (R, Y, B)
Total Harmonic Distortion for all three phases — identifies power quality issues and harmonic-driven heating.
4
Ambient Temp & Humidity
Environmental conditions inside the switchgear cabinet — critical for corrosion prevention and safe operation.
5
Temperature in Cable Compartment
Cable compartment temperature (R, Y, B) — detects hot joints, overloads, and insulation degradation early.
6
Humidity in Cable Compartment
Humidity levels inside cable compartment — helps prevent moisture-induced arcing and corrosion of connectors.
7
Oil Temperature
Oil temperature for oil-filled switchgear — overtemperature conditions signal insulation failure risk in MV equipment.
8
Oil Level
Real-time oil level tracking — low oil levels increase thermal stress and can accelerate equipment aging.
Monitoring Benefits

How SGMS Helps Overcome
Switchgear Issues

Continuous multi-parameter monitoring supports early fault detection, helps prevent unplanned outages, and supports the operational life of your switchgear assets.

Thermal Overload Prevention

Continuous cable and busbar temperature monitoring detects hotspots before thermal failure — alerts trigger the moment temperatures exceed safe thresholds across any phase.

Predictive Maintenance

Moisture & Corrosion Control

Dual humidity sensors in the cable compartment and ambient zone detect moisture ingress before it causes arcing, corrosion, or insulation failure in critical termination points.

Corrosion Guard

Power Quality & THD

THD analysis across R, Y, B phases identifies harmonic distortion causing overheating, equipment stress, and reduced lifespan — supporting compliance with power quality standards.

THD Analysis

Oil Health Monitoring

For oil-filled switchgear, continuous oil temperature and level monitoring helps prevent dry-out conditions — a leading cause of major failures in medium and high-voltage systems.

Oil Health

Energy & Load Monitoring

Real-time V, I, PF and energy parameter tracking helps ensure loads stay within safe limits — supporting prevention of overload conditions that accelerate insulation degradation and mechanical wear.

Load Guard

Instant Multi-Channel Alerts

When any parameter exceeds configured thresholds, SGMS instantly dispatches SMS and email alerts to up to 5 stakeholders — enabling faster response before anomalies become outages.

FAQ

Frequently asked questions

What parameters does SGMS monitor on a switchgear panel?

SGMS monitors 8 key parameters per unit: voltage, current and power factor; energy (kWh/kVAh/kVARh); THD for current and voltage across R, Y, B phases; ambient temperature and humidity; cable-compartment temperature and humidity; and, for oil-filled switchgear, oil temperature and oil level.

Can SGMS detect moisture ingress before it causes corrosion?

Yes. Dual humidity sensors track both the cable compartment and ambient cabinet air, so rising moisture levels are visible on the dashboard before they progress to corrosion or arcing.

Does SGMS work with oil-filled switchgear?

Yes. SGMS includes dedicated oil temperature and oil level monitoring for oil-filled switchgear, where low oil level or rising temperature are early indicators of insulation stress.

How does SGMS detect THD-related power quality issues?

SGMS continuously measures Total Harmonic Distortion for both current and voltage across the R, Y and B phases, flagging harmonic distortion that can cause overheating and reduced equipment life.

How many stakeholders can receive SGMS alerts?

SGMS can dispatch instant SMS and email alerts to up to 5 configured stakeholders whenever a monitored parameter crosses its threshold.

How is SGMS different from periodic switchgear inspection?

Periodic inspection captures a single point-in-time reading, typically during scheduled maintenance. SGMS streams 8 parameters continuously and raises alerts as soon as a threshold is crossed, so degradation such as rising temperature or humidity is caught between inspection cycles.

Predictive Switchgear Intelligence

Switchgear failures are rarely sudden — they develop over days or weeks through subtle changes in temperature, humidity, and power quality. By the time a fault causes a shutdown, the warning signs were often present for weeks.

SGMS's continuous 8-parameter monitoring captures these early warning signals and presents them on a unified dashboard — helping maintenance teams intervene proactively, schedule work during planned shutdowns, and reduce costly unplanned downtime across switchgear assets.
