The Swartz type 82 reclosing relay is part of a solid-state reclosing system that will prevent the reclosing of a PC breaker on a faulted line. These systems work to protect electrical equipment and personnel as well as remain electrically compliant in the locomotive and heavy freight industry. When a fault in her overcurrent trip occurs, relays will provide a load site for verification before breakers will close and automatically reclose the breaker along a clear line.
This type of relay is designed and suited for heavy and light rail installation. The features include a dropout construction and LED meter as well as a bidirectional load measuring support system. Voltage compensation as well as an internal power supply for auto compensation in DC output offers several checks and balances for any situation. Reclosing systems are made up of two units including the solid-state transducer and the reclosing relay. Transducers are self-powered units that will send skilled but voltages to the relay and the relay will be remotely mounted from the transducer of eliminating exposure to any type of traction voltage that could occur. Relays will respond to the input and perform functions on load measurements, sequencing, indication, and voltage measurement. Relays can handle all load side and breaker functions and then pick up the electrical current based on preset values closing the breaker.
The value of the relay measures the minimum feeder resistance an adjustment can occur at every level of the sequence to ensure greater protection or to monitor for dead load pickup and other safety concerns. These are robust monitors that are seeing used in many worldwide trades and light rail solutions.
