We do
Electrical work
Our team has been working with commercial electrical for many years now and have the experience to repair, replace, survey, test, and maintain complex electrical units. Explore our services in depth to find what you’re interested in.
Analytical Surveys
Arc Flash Survey
This is an evaluation of the risk of an arc flash incident, which is an explosive release of energy caused by an electrical current flowing through the air between conductors. The survey determines the incident energy to which a worker may be exposed and how to protect the worker from an arc flash accident and other electrical hazards1.
Infrared Thermographic Survey
This is a non-destructive testing method that uses infrared cameras to measure surface temperatures and detect thermal defects and air leakage in building envelopes. The survey can help prevent serious injuries, equipment damage, and energy loss caused by overheating, fire, or moisture problems2.
Circuit Tracing & Panel Labeling
This is a process of identifying and labeling the electrical circuits and breakers in a panel. The survey helps to ensure the safe operation and maintenance of the electrical system, especially in an emergency. The survey also avoids the use of improper or unsafe methods for opening, reversing, or closing circuits under load conditions3.
Protective Device Coordination Study
This is an analysis of the characteristics, ratings, and settings of overcurrent protective devices, such as relays, fuses, and circuit breakers, and the circuits they protect. The study aims to provide adequate protection for the electrical equipment and minimize service interruption under overload and short-circuit conditions4.
Short Circuit Study
This is an evaluation of the electrical system’s capacity to determine the magnitude of currents that can flow through the electrical network and equipment during an electrical fault. The study compares the fault currents to the ratings of installed equipment and short circuit protection devices. The study helps to avoid equipment damage or failure, fire hazards, and personnel injuries caused by excessive currents5.
Testing Services
Substation Testing
This service involves testing the performance and reliability of substation equipment, such as circuit breakers, transformers, switchgear, protection relays, and grounding systems. Substation testing can help prevent failures, improve safety, and optimize efficiency. Some of the tests we perform include insulation resistance, power factor, winding resistance, ratio, polarity, impedance, contact resistance, timing, and functional tests
Control & Automation Testing
This service involves testing the functionality and communication of control and automation systems, such as programmable logic controllers (PLCs), distributed control systems (DCS), supervisory control and data acquisition (SCADA), human-machine interfaces (HMIs), and smart devices. Control and automation testing can help verify the logic, sequence, interlocks, alarms, and data transfer of these systems. Some of the tests we perform include input/output tests, loop tests, simulation tests, network tests, and cyber security tests.
Breaker Testing
This service involves testing the operation and condition of low-voltage and medium-voltage circuit breakers. Breaker testing can help ensure the proper functioning and coordination of the breakers in case of faults or overloads. Some of the tests we perform include resistance tests, timing tests, travel tests, contact wear tests, coil tests, and trip unit tests
Transformer Testing
This service involves testing the electrical characteristics and parameters of power transformers. Transformer testing can help assess the quality and performance of the transformers and detect any defects or deterioration. Some of the tests we perform include ratio tests, polarity tests, winding resistance tests, insulation resistance tests, dielectric tests, impedance tests, load loss tests, no-load loss tests, temperature rise tests, and dissolved gas analysis.
Relay Testing
This service involves testing the functionality and settings of protection relays. Relay testing can help ensure the correct operation and coordination of the relays in protecting the electrical system from faults or abnormal conditions. Some of the tests we perform include pickup tests, timing tests, slope tests, harmonic restraint tests, directional tests, distance tests, differential tests, and communication-assisted trip schemes
Ground Testing
This service involves measuring the resistance and impedance of the grounding system. Ground testing can help evaluate the effectiveness and safety of the grounding system in dissipating fault currents or lightning strikes. Some of the methods we use for ground testing include fall-of-potential method, stakeless method, selective method, soil resistivity method, clamp-on method, and touch potential method
Cable Testing
This service involves verifying the integrity and performance of power cables. Cable testing can help identify any faults or defects in the cable insulation or joints. Some of the methods we use for cable testing include continuity test, insulation resistance test, high potential test (HiPot), very low frequency test (VLF), partial discharge test (PD), time domain reflectometry (TDR), frequency domain reflectometry (FDR), dissipation factor test (DF), and cable fault location
Maintenance Programs
Preventative Maintenance
This is a proactive approach to maintaining the optimal condition and performance of electrical equipment and systems. Preventative maintenance involves regular inspections, tests, repairs, adjustments, lubrication, cleaning, and replacement of parts before they fail or cause problems. Preventative maintenance can help reduce the risk of breakdowns, accidents, injuries, and costly repairs.
Programs for High & Low voltage systems
These are customized plans to ensure the safety, reliability, and efficiency of electrical systems that operate at different voltage levels. High voltage systems are those that operate above 1000 volts AC or 1500 volts DC, while low voltage systems are those that operate below these thresholds.
Emergency Lightining System Maintenance
This is a process of ensuring the proper functioning and compliance of emergency lighting systems in case of a power outage or an emergency situation. Emergency lighting systems are designed to provide illumination for safe exit and evacuation of occupants from a building or facility.
Generator Maintenance
This is a process of keeping a gas or diesel generator in good working order through regular checks and services. Generators are devices that convert mechanical energy into electrical energy for backup or emergency power supply.
Install & Replacement
Switchgear Installation
Switchgear is a device that protects and controls electrical circuits and equipment. Switchgear installation involves connecting the switchgear to the power source, the load, and the grounding system, as well as testing and commissioning the switchgear.
Transformer Installation
Transformers are devices that change the voltage and current of an electrical power supply. Transformer installation involves selecting the appropriate type, size, and location of the transformer, as well as preparing the foundation, wiring, cooling system, and protection devices.
