Schneider Electric Expert Diagnostics Program Used by Field Service Representatives

Performing Diagnostics of MasterPact Devices with Schneider Electric

Schneider Electric offers a large portfolio of manufacturer diagnostic services for electrical distribution equipment.

Enhanced Manufacturer Maintenance by Schneider Electric is condition-based maintenance where inspection and/or testing, analysis, and the ensuing maintenance actions are conducted on site. Testing, analysis, and ensuing recommended maintenance actions for low voltage (LV) circuit breakers and switch-disconnectors, for example MasterPact NT/NW devices, are provided by the following diagnostics programs:

• ProDiag Trip Unit

• ProDiag Breaker

• ProDiag Clusters

The ProDiag diagnostics programs deliver a comprehensive report with data collected during testing, along with expert recommendations based on analytics. This enables you to anticipate downtime and improve the availability of your installation.

Contact your Schneider Electric field service representative for more information.

ProDiag Trip Unit

Designed by Schneider Electric, ProDiag Trip Unit is used to perform diagnostics of circuit breaker control unit tripping performance.

Accurate tripping time operation in accordance with control unit settings defined for an electrical installation is now a strategic function for evaluating protection performance. Fault detection and tripping speed reaction stops short-circuits from creating high incident energy levels.

ProDiag Trip Unit can help to mitigate the risks of potential failure of LV circuit breaker control unit performance by:

• Detection of tripping time drifts.

• Verification of LV circuit breaker and control unit features according to electrical network characteristics (breaking capacity, discrimination).

• Analysis of the history of alarms and events.

Non-performing LV circuit breaker control unit causes unwanted effects such as:

• Unintended trips (power outage).

• Downstream industrial equipment inefficiencies.

• Breakdowns.

• Longer short-circuits (overheating and internal fires).

• Circuit breaker and switchgear destruction, or even complete destruction of the electrical room.

ProDiag Trip Unit helps the end user to discover and understand LV circuit breaker control unit performance and criticality. Diagnosis is conducted on de-energized LV circuit breaker and only by Schneider Electric field service representatives.

Regular diagnosis of LV circuit breaker control unit tripping performance is delivered with theComplete Manufacturer Maintenance program. This solution brings the end user the following benefits:

• Help ensure the protection of downstream LV electrical distribution equipment, goods, and people operating them.

• Enhance reliability, mitigating unintended shutdown risks and operating costs.

• Extend the equipment lifespan, optimizing the total cost of ownership.

ProDiag Breaker

Designed by Schneider Electric, ProDiag Breaker diagnostics evaluate the performance of opening, closing, and spring charging operations.

A quick and reliable opening of LV circuit breaker is a strategic function for evaluating the complete operating chain. The fault detection rate and reaction speed stops short-circuits from creating high incident energy level.

ProDiag Breaker is used to mitigate the risk of LV circuit breaker electro-kinematic incident. ProDiag Breaker identifies the symptoms of undetected incident or degradation of the equipment that can cause unwanted effects like:

• Stress on internal moving parts.

• Accelerated wear of internal moving parts.

• Overheating and/or internal fires.

• Circuit breaker and switchgear destruction.

• Electrical room complete destruction.

ProDiag Breaker is conducted on de-energized LV circuit breaker and only by Schneider Electric field service representatives.

Regular diagnosis of electric and kinematic performance of LV circuit breakers is delivered with the Advanced Manufacturer Maintenance program. This solution brings the end user the following benefits:

• Alert in the early stages of above described phenomena not detected during regular preventive maintenance.

• Help ensure the protection of downstream LV electrical distribution equipment, goods, and people operating them.

• Enhance reliability, mitigating unexpected shutdown risks and operating costs.

• Extend the equipment lifespan, optimizing the total cost of ownership.

ProDiag Clusters

Designed by Schneider Electric, ProDiag Clusters is used to diagnose early stages of connection cluster deterioration not detected during regular preventive maintenance. This deterioration can result from one or more of the following factors:

• Severe environmental conditions

• User application with high criticality

• Accelerated aging process caused by racking-out and racking-in operations

• Electrical stress

• Uneven maintenance
