An essential service

In nuclear power stations, reverse engineering of obsolete electro-mechanical relays and their replacement with solid state relays of identical fit and functionality can lead to significant savings and performance improvements.

In many cases, reverse engineering of an electro-mechanical relay becomes necessary when the original manufacturer stops manufacturing the device, no spare parts can be obtained, and no design drawings or documentation are available. 

A rigorous process

Kinectrics offers extensive experience in the reverse engineering process, which typically involves the following steps:

• Need Identification
• Device Functionality Review
• Design and Development of Prototype
• Testing
• Production
• Documentation

Advanced prototyping by Kinectrics

Kinectrics’ prototype design and development involves preparation of technical specifications, device design, search for component suppliers and confirmation of quality standards, procurement of components and assembly of the required number of prototype samples. If an upgrade of the materials and components from original designs is practical and desirable, it is incorporated into the specifications. In many cases, microprocessor-based devices are used in place of original electro-mechanical relays, and fitted with ancillary electronic components to provide required functionality.

Comprehensive testing

Kinectrics develops a test plan in consultation with the client and the prototype samples are then put through rigorous testing in our lab facilities. In the case of relays, testing will include steady state and dynamic testing using Kinectrics’ Real Time Digital Simulator (RTDS), environmental testing including surge withstand, RF testing, dielectric testing, seismic testing, temperature and voltage withstand tests, per applicable test standards. Clients are welcome to witness the test sessions.

After the prototype has successfully passed the tests, production of the unit begins under strict quality controls. Inspections are carried out during the production phase and required production tests are performed on the completed units, which are then suitably labeled.

Complete documentation

Complete documentation for the device is prepared by Kinectrics; including a device design manual and drawings, maintenance and operation manual, device component lists, spare parts list, commissioning procedures, test procedures and test results.
