What We Offer:
Our maintenance solutions are designed for accuracy, compliance, and zero compromise on safety.
1. Changeover Scheme Maintenance
Reliable Operation of Power Transfer Systems
At Pro-Active Solutions, we offer specialized maintenance services for manual and automatic changeover schemes, ensuring reliable switching between primary and secondary power sources — such as utility supply and backup generators.
Key Maintenance Activities Include:
- Functional Testing of Changeover Systems
Verifies proper transition between sources under load and no-load conditions. - Control Wiring & Logic Inspection
Checks wiring integrity, control logic, and interlocks to avoid faulty switching. - Load Balancing & Transfer Time Assessment
Evaluates load handling during transfer and ensures minimal downtime. - Safety Interlock Verification
Confirms the proper operation of electrical and mechanical interlocks to prevent simultaneous source connection. - Manual & Auto Mode Testing
Tests all modes of operation for both manual and automatic changeover mechanisms.
Why It Matters:
Regular maintenance of changeover schemes ensures uninterrupted power supply, reduces equipment stress during switching, and enhances system safety. It is essential for critical infrastructure, industrial plants, and any setup relying on backup power.
2. Protection Scheme Maintenance
Ensuring Fault Detection and System Integrity
At Pro-Active Solutions, we provide comprehensive maintenance services for electrical protection schemes — the critical first line of defence against faults and system failures. Our approach ensures all protective relays, logic circuits, and control elements function accurately and reliably under real-world conditions.
Key Maintenance Activities Include:
- Relay Functionality Verification
Tests and calibrates protective relays (numerical & electromechanical) to ensure correct fault detection and isolation. - Trip Circuit & Interlock Testing
Checks the continuity and operation of trip circuits and interlocks involved in fault interruption. - Protection Logic Review & Validation
Confirms that protection logic and settings are aligned with system coordination and fault study results. - Backup Protection Check
Verifies secondary protection paths to ensure fail-safe operation if the primary scheme fails. - Event Recording & Analysis Review
Downloads and evaluates relay event logs and fault records to assess past performance and fine-tune settings.
Why It Matters:
Properly maintained protection schemes prevent widespread outages, minimize damage during electrical faults, and ensure system stability and personnel safety. Regular servicing improves response accuracy, maintains regulatory compliance, and supports fast recovery in case of incidents.
3. Grid Islanding Scheme Maintenance
Safeguarding Power Continuity and Grid Stability
At Pro-Active Solutions, we offer specialized maintenance services for Grid Islanding Schemes — systems designed to automatically isolate a portion of the power network during grid failures or disturbances. These schemes are crucial for ensuring uninterrupted operation in critical facilities like industrial plants, data centers, and captive power setups.
Key Maintenance Activities Include:
- Islanding Logic Verification
Validates the operational logic and parameters that trigger automatic disconnection and reconnection from the grid. - Synchronism & Load Shedding Checks
Ensures seamless transition to islanded mode with load prioritization and controlled reconnection. - Relay & Controller Testing
Tests frequency, voltage, and ROCOF (Rate of Change of Frequency) relays involved in islanding operations. - Transfer Scheme Coordination
Assesses coordination between grid, generator, and load management systems to avoid unwanted islanding or blackouts. - Fail-Safe Operation Testing
Simulates fault scenarios to confirm reliable protection and reconnection behaviour.
Why It Matters:
Maintaining your grid islanding scheme ensures uninterrupted power supply during grid outages, protects sensitive equipment, and supports regulatory compliance with grid codes and safety standards. It’s vital for power reliability, load stability, and operational resilience.
4. Load Shedding Scheme Maintenance
Ensuring Stable Power During Critical Conditions
At Pro-Active Solutions, we maintain and fine-tune Load Shedding Schemes that are essential for protecting electrical systems from overload and instability. These automated schemes intelligently reduce non-essential loads during underfrequency or overload conditions to maintain grid balance and prevent system collapse.
Key Maintenance Activities Include:
- Under frequency Relay Testing
Validates relay settings and functionality to ensure accurate detection of grid frequency drops. - Load Prioritization Review
Confirms correct sequence and grouping of loads based on operational criticality and shedding logic. - Interlocking & Trip Path Testing
Ensures reliable operation of breakers, interlocks, and signalling paths used during load shedding events. - Scheme Coordination Check
Verifies that load shedding integrates seamlessly with generator control systems, protection schemes, and SCADA (if applicable). - Simulated Load Shedding Drills
Performs real-time or simulated tests to evaluate response time, logic execution, and recovery behaviour.
Why It Matters:
Effective load shedding scheme maintenance prevents blackouts, protects generators from overloading, and ensures critical operations stay online. It also supports grid code compliance, improves system resilience, and minimizes recovery time after disturbances.
