Services

SUNERTECH CORPORATION primarily serves electric power industry that includes Generation, Transmission and Distribution companies in the government and private sectors. With the growing demands for a safer, more realiable and economical electric power in the country, Sunertech strengthens its commitment to provide advanced system integration and innovative solutions and services such as:

    Electrical Equipment Testing

    Primary Equipment

  • Power Transformer
  • Instrument Transformer
  • Insulation & Power Factor Testing
  • Line Impedance Measurement

    Secondary Equipment

  • Protection Relays
  • Meters
  • Transducers

The condition of the insulation is essential for secure and reliable operation of your transformer. Measuring capacitance and dissipation/power factor helps you to determine insulation condition in bushings or between windings. Changes in capacitance can, for example, indicate mechanical displacements of windings or partial breakdown in bushings. Aging and degradation of the insulation, coupled with the ingress of water, increase the amount of energy that is converted to heat in the insulation. The rate of these losses is measured as dissipation factor.

A protective relay is a device that monitors system conditions (amps, volts, etc., using CTs and PTs) and reacts to the detection of abnormal conditions. The relay compares the real-time actual quantities against preset programmable threshold values, and sends DC electrical control signals to trip circuit breakers or other opening devices in an effort to clear an abnormal condition on the equipment it is protecting. When system problems are detected and breakers are tripped, alarm indications are sent to system control and sometimes other protection operations are initiated. As a result, equipment may be deenergized, taken off line, and consumers will be out of power with minimal equipment damage. The operation of protective relays is the stabilizing force against the unwanted destabilizing forces that occur in electric power systems when something happens, such as unanticipated power faults and lightning strikes.


  • Automation and Integration

    We offer technologies, products, systems, and services that address the entire application spectrum, from communicating with a single relay to integrating and automating the metering, control, reporting, and protection for a large system. We provide networking, control, and communications solutions to integrate devices for data acquisition plus remote and local control. We design, develop, test, and deploy complete supervisory control and data acquisition (SCADA) systems to monitor and control systems or processes. We have experiences in providing various system sizes, ranging from simple standalone to complex networked systems. We design SCADA systems to assist with outage management, asset optimization, just-in-time (JIT) maintenance, load shedding, load restoration, access control, cybersecurity, and more. Our knowledgeable engineers will work with your operations requirements, preferred software, and existing equipment to create a SCADA solution that is right for you.

  • Calibration Test Equipment

    Cyber Security Services

    Cyber Security Services

    SEL cybersecurity services help customers assess, support, and develop control system security infrastructure. Our services support NERC (North American Electric Reliability Corporation) Critical Infrastructure Protection (CIP) standards as well as other security standards and regulations. SEL personnel have multidisciplinary experience in substations, control systems, and information security, and maintain multiple industry security certifications.

    Autosynchronization System

    Autosynchronization System

    SEL Autosynchronization Systems measure voltage and frequency on both the generator and the utiliy system, send proportional correction pulses to adjust the governor and exciter as necessary, and automatically close the breaker on synchronization. This process enables safe, secure, unattended synchronization of generation onto the power system.

    Distribution Automation Control System

    Distribution Automation Control System

    Automate feeder restoration and reduce outage times with the SEL Distribution Automation Control System. The systen analyzes and detects fault conditions, isolates affected feeder sections, and restores power to unaffected sections. The system includes simple drag-and-drop IEC 61131 function block configuration software on an SEL information processor, with the ability to automate up to six sources and 100 devices.

    Model Power System Testing

    Model Power System Testing

    Improve power system performance in critical applications, validate relay performance, and optimize settings using model power system testing. SEL creates a computer model of your power system, enabling endless possibilities for testing protection and control systems under realistic conditions using a Real Time Digital Simulator (RTDS®). A typical simulation of 500–1,000 fault cases can be run in less than one day, providing the equivalent of many years of operating history, which allows you to gain insight into the limits of your system.

    Power Management Solutions

    Power Management Solutions

    Maximize system uptime and mitigate problems before you experience an outage with proactive, high-speed load shedding, generation control, voltage control, and load management. powerMAX provides total system awareness through graphical user interfaces, automatic waveform capture, report analysis software, and report generation tools.

    Protection & Automation Services

    Protection & Automation Services

    SEL protection and automation services have been implemented in power systems around the world. SEL engineers approach each new project with years of experience and a broad knowledge base, which provide the best solution for your system. • Scheme design • Relay settings • HMI design and programming • Communications architecture design and programming • Field testing and commissioning • Fault and coordination studies

    SCADA System Solutions

    SCADA System Solutions

    SEL designs, develops, tests, and deploys complete supervisory control and data acquisition (SCADA) systems to monitor and control your systems or processes. We have experiences in providing various system sizes, ranging from simple standalone to complex networked systems. We design SCADA systems to assist with outage management, asset optimization, just-in-time (JIT) maintenance, load shedding, load restoration, access control, cybersecurity, and more. Our knowledgeable engineers will work with your operations requirements, preferred software, and existing equipment to create a SCADA solution that is right for you.

    Synchrophasor Systems

    Synchrophasor Systems

    Synchronized phasor measurements (synchrophasors) provide a real-time measurement of electrical quantities from across a power system. SEL can help you apply these measurements to validate system models, measure stability margin, maximize stable system loading, and implement remedial action schemes (RAS).

    Power System Studies

    Power System Studies

    SEL provides power system studies for small to large electric utilities, independent power producers, and industrial plants. SEL can help you better understand your power system, identify deficiencies, provide analysis and recommendations to improve performance, and comply with electrical standards and codes.

    Arc-Flash Hazard Services

    Arc-Flash Hazard Services

    SEL conducts flexible, customized arc-flash hazard services to mitigate arc-flash hazard risk, improve employee safety, and address OSHA regulations (29 CFR 1910) and the National Fire Protection Association Standard for Electrical Safety in the Workplace (NFPA 70E). SEL uses proven methods to calculate flash-protection boundaries and classify each area into proper personal protective equipment (PPE) categories, among many other services for providing a complete, cost-effective arc-flash solution for your facility.
