JEDDTECH provides cost-effective retrofitting and modernization solutions that extend the service life of existing electrical infrastructure while minimizing capital expenditures and operational disruptions. Our extensive experience in substation and power plant rehabilitation enables asset owners to improve system reliability, safety, maintainability, and performance without the need for complete equipment replacement.
By carefully evaluating the condition of existing equipment, JEDDTECH develops retrofit solutions that maximize the reuse of serviceable assets while integrating modern technologies and equipment.
Many existing switchgear installations remain structurally sound and operational even though one or more circuit breakers have become obsolete, unreliable, or costly to maintain. Examples include aging Oil Circuit Breakers (OCBs), Air Circuit Breakers (ACBs), and other legacy breaker technologies for which spare parts are scarce or no longer available.
JEDDTECH can replace these obsolete breakers with modern Vacuum Circuit Breakers (VCBs) or other suitable technologies while retaining the existing switchgear lineup whenever feasible. Our retrofit solutions include:
- Engineering assessment of existing switchgear and breaker compatibility
- Mechanical and electrical adaptation of new breakers to existing cubicles
- Modification of control and protection circuits as required
- Site testing of retrofitted equipment
- Installation and commissioning with minimal plant or substation downtime
- Improved reliability, safety, and ease of maintenance
This approach significantly reduces project costs and outage durations compared to complete switchgear replacement.
Many substations and power plants continue to operate with electromechanical or first-generation electronic relays that have become obsolete, difficult to maintain, or no longer meet current protection requirements.
JEDDTECH specializes in replacing aging protection relays with modern microprocessor-based Intelligent Electronic Devices (IEDs) while preserving as much of the existing installation as possible. Our relay retrofit services include:
- Replacement of electromechanical and obsolete static relays
- Upgrade to modern numerical protection relays
- Re-engineering of protection schemes when required
- Integration with existing control, monitoring, and SCADA systems
- Wiring modifications and relay panel enhancements
- Protection testing, commissioning, and documentation updates
This modernization improves protection performance, fault analysis capabilities, system monitoring, and communication functions while minimizing modifications to the existing equipment and wiring.
Through our retrofit and modernization services, JEDDTECH helps utilities, industrial facilities, and power generation companies maximize the value of their existing assets while achieving the benefits of modern protection, control, and switching technologies.
JEDDTECH is one of the Philippines’ leading providers of System Integrity Protection Scheme (SIPS) solutions for the electric power industry. With extensive experience in power system protection, control, communications, and automation, we deliver complete turnkey SIPS solutions that enhance grid reliability, stability, and security.
A SIPS is a specialized wide-area protection and control system designed to detect critical power system conditions and automatically initiate corrective actions to prevent cascading outages, system instability, equipment damage, or widespread blackouts. These systems play a vital role in maintaining the secure operation of interconnected transmission networks, especially as power systems become more complex and heavily loaded.
JEDDTECH provides comprehensive SIPS services including:
- System studies and protection scheme design
- Engineering and detailed design
- Supply of protection, control, communication, and automation equipment
- Panel design and fabrication
- Integration with SCADA, EMS, and substation automation systems
- Communication network design and implementation
- Factory Acceptance Testing (FAT)
- Site installation, testing, and commissioning
- Training, documentation, and post-implementation support
Our flagship SIPS project was the SIPS for the Mindanao–Visayas Interconnection Project (MVIP), one of the most significant transmission projects in the Philippines. Under this project, JEDDTECH successfully designed, supplied, integrated, tested, and commissioned the System Integrity Protection Scheme that supports the reliable operation of the country’s first interconnection between the Mindanao and Visayas power grids.
This landmark project demonstrates JEDDTECH’s capability to execute complex, mission-critical protection and control systems that meet the stringent requirements of modern transmission utilities. Through our expertise in protection relays, communication systems, SCADA integration, and power system automation, JEDDTECH continues to help utilities maintain grid stability, improve operational reliability, and support the growing demand for secure and resilient power networks.
