Summary
This study introduces an Internet of Things (IoT) system for real-time microclimate monitoring in electrical switchgear. The system enables predictive maintenance, significantly reducing electrical station malfunctions and lowering maintenance costs.
Area of Science:
- Electrical Engineering
- Environmental Monitoring
- Internet of Things (IoT)
Background:
- Unfavorable microclimate conditions (humidity, dust) in switchgear can cause electrical discharges and equipment failure.
- Current maintenance practices may not adequately address environmental risks, leading to unplanned interventions and high costs.
Purpose of the Study:
- To develop and evaluate an IoT-based system for real-time microclimate monitoring in Low Voltage/High Voltage switchgear.
- To enable predictive maintenance strategies for electrical substations.
Main Methods:
- Implementation of a low-cost, efficient IoT platform (PRTG) for remote climate monitoring.
- Continuous data collection of environmental conditions (humidity, dust) inside and outside switchgear over a 365-day period.
Main Results:
- Successful integration of the IoT monitoring system into switchgear maintenance processes.
- Demonstrated reduction in maintenance costs through proactive environmental management.
Conclusions:
- The proposed IoT system effectively monitors switchgear microclimates, preventing malfunctions.
- Predictive maintenance enabled by this system leads to significant cost savings and improved operational reliability.

178
Automatic circuit reclosers enhance the protection of distribution circuits by interrupting and auto-reclosing an AC circuit according to a preset sequence. They effectively manage temporary faults on overhead distribution lines, often caused by tree limbs or wildlife, by briefly disrupting service to improve overall reliability. However, contact with reclosers or energized broken conductors on the ground can pose serious hazards.

01:25Distribution Reliability and Automation
173
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

01:23Insulation Coordination
242
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times...

01:25Power System Distribution
342
Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.

263
Conducting a three-phase short circuit test on an unloaded synchronous machine helps understand its impact on the system. The AC fault current's oscillogram, with the DC offset removed, reveals that the waveform amplitude decreases from an initially high value to a steady-state level for one phase of the machine.
This behavior occurs due to the magnetic flux produced by the short-circuit armature currents. Initially, these currents follow high-reluctance paths but eventually shift to...

Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.
