ADVANCED MOTOR PROTECTION RELAY WITH IMPORTANT SAFETY BENEFITS
Product News Thursday, June 13, 2013: NewElec (Pty) Ltd
The ProLoc L.V motor protection and management relay is the brainchild of EMIS in Heidelberg. Developed by NewElec, the relay enhances the protection and safety aspects desired by clients in the coal mining environment. It comprises two separate but inter-related components: the panel mounted protection relay incorporates four inputs and two outputs; and the door mounted MMI provides a further three output contacts.
In order of importance, the design emphasis is on improving the safety of users exposed to dangerous electrical shock. The relay incorporates features such as earth insulation lock out, frozen contactor pole detection and lock out, running earth leakage protection, earth fault detection and back-tripping. It also provides short circuit detection with enhanced trip time and fault level.
The relay provides ease of paramatization as the MMI stores up to five different settings with its associated logic functions. The user is able to switch from one motor setting to the next with a few button presses.
In addition, the relay features starter intelligent functions with user selectable labeling to rapidly identify motor kW and trip conditions. Motor management functions including event and fault records can be downloaded by the user.
With Profibus communications, ProLoc offers powerful motor protection benefits and logic functions that control start and trip sequences. A useful emulator / simulator runs with the free ‘front-end’ software providing a training platform for the electrician.
