How Do Breaker Testers Work?
Breaker testers function by using sensors to capture key data during the opening and closing cycles of circuit breakers. The devices measure parameters such as switch timing, travel, and resistance. These readings are processed by high-speed processors, with results displayed on screens and printed for maintenance logs.
Wrindu’s testers utilize advanced sensors, including laser technology for greater precision, especially in SF6 and vacuum circuit breakers. These testers help identify potential faults in advance, making them crucial for predictive maintenance in power grids and substations.
Steps:
-
Attach sensors to the breaker contacts.
-
Use the integrated power supply to energize the circuit.
-
Perform tests while the software automatically calculates speed and other metrics.
-
Export data for further analysis and record-keeping.
This process supports the early detection of issues, preventing major power failures.
