Proper maintenance testing is essential to keep protective systems in good working condition. A solid maintenance program helps identify the root cause of system events, avoid costly emergency repairs and maintain a safe working environment.
A comprehensive maintenance test includes relay testing, full circuit integrity and functional testing of protection systems. This type of testing assists in evaluation and health analysis of customer equipment.
The North American Electric Reliability Corporation (NERC), defines mandatory requirements for periodic maintenance of essential power systems related to the Bulk Electric System or BES. While preventative maintenance is not required for general, non BES loads, it is recommended as an industry best practice. This method of testing includes the following services:
- Evaluation and health analysis of customer equipment
- Full elemental testing (by customer request)
- Functional testing of protection systems (Dynamic when possible)
- Regulatory support for systems that fall under NERC standards
- Customized documentation of testing activities
- Enhanced documentation for regulatory evidence
