What is the purpose of the thermocouples in the load test?

Thermocouples are sensors used to measure temperature by generating a voltage in response to temperature changes at the junction of two different metals. In the context of a load test, they are strategically placed in critical locations where excess heat may be generated due to electrical resistance or other factors during the operation of electrical systems.

The primary purpose of using thermocouples in load testing is to monitor and record these temperature changes to ensure that components are operating within safe limits. High temperatures could indicate problems such as excessive current flow, poor connections, or inadequate cooling, which could lead to equipment failure or safety hazards. By recording temperature in these critical locations, technicians can assess the thermal performance of the system and make adjustments as necessary to ensure safe and efficient operation.

This monitoring helps prevent overheating of electrical components, which is essential for maintaining reliability and longevity in marine electrical systems.
