DC 82 | Type 82 DC Re-closing Relay

DC 82 Our DC 82 relay is a Reclosing technology that’s part of a solid-state system preventing the DC closure on a faulted line. After an overcurrent trip occurs or the fault is tripped the relay provides a load side verification of fault. This re-closes the breaker for a clear line. Our version of the type 82 relay is designed for use on a wide range of heavy rail and light rail systems.

Our Reclosing System

The DC 82 system is built on two main units including the DC reclosing relay and the Swartz solid-state transducer. The transducer is a self powered unit that will then send out converted and properly scaled bias voltages through to the relay. The relay can also be remotely mounted to eliminate the overall exposure to traction voltage through the transducer.

Relays respond to input performing voltage measurements and shutoff functions as required. As well as voltage measurements, the relay also handles sequencing an indication as well as load measurements. The main relay measures voltage on the load side as well as picks up voltage in preset values in order to close breakers on clear lines. Relays will continue to maintain voltage measurements in a pre-existing format and provide a differential voltage in load measuring applications. A differential voltage at a preset value can close the breaker as a safety mechanism. A set value on the relay has load measuring current with a minimum resistance. Regular adjustments within each step of the sequence can make sure that debt load pickup occurs and that all levels can be well regulated.

The Main Features Of The DC 82 Relay

Including a draw out construction, this advanced version of the DC 82 relay includes a bidirectional load measuring feature as well. The LED meter is extremely accurate and easy to read and the voltages on the system performs well with extensive reliability.

Voltage compensating also occurs on this unit and the internal power supply operates and auto compensates for many ranges of DC inputs. With the built-in features for calibration and a widely intelligent design, this is a device that features not only a modular construction but a wide range of auto compensation.

Capable of operating at a temperature of up to 55°C and as low as -20°C, this is a device that can be suited for almost any type of environment. Whether it is mounted in exterior or interior format it continues to perform time and time again. Remote mounting technology ensures that it’s easy to eliminate the chance for exposure or traction voltage. In eliminating interference and opting for space saving through the remote mounting can make sure that the system can be easily maintained.

LEDs semaphores ensure quick readout during diagnostics. With a larger LED display, the relay can simplify processes for technicians, assisting with the process of calibration. If you are seeking a relay that can handle all day-to-day functions for light and heavy rail as well as offer unprecedented performance, Our DC 82 relay is the ideal solution for your Traction Power System.
