In any high voltage applications, there needs to be a series of monitoring and support tools that can assist mining professionals. One such tool is the ground monitor. A ground monitor helps to ensure that there is a consistent and reliable flow of electricity in a circuit. Not only does this keep the mining equipment and vehicles running smoothly, but it can also help to prevent accidents.
A ground monitor works by constantly checking the electrical current in a circuit. If there is any disparity or irregularities, the ground monitor will automatically trip the circuit breaker. This shuts off the flow of electricity to prevent any potential damage or accidents.
Our low voltage continuity ground monitor is a combination of a continuity ground monitor and a zero sequence type ground trip system. This is the ideal choice for most small to medium-sized mining applications.
The ground monitor portion of the relay will check on the normal performance of the pilot/ground circuit. If the pilot/ground circuit is interrupted for any reason, the GM relay will activate, regardless of impedance increases.
The monitor will not drift out during a 25% voltage drop in the pilot ground loop and will survive a power outage for 1⁄4 second when protected by 1/2 ohms.
The ground fault portion of the combination relay will check the ground fault current and trip the circuit breaker if it rises too high. It's suitable for use with shunt trips or under-voltage devices, and it may be used with most standard transformers.
Through the combination of these two monitors, you can be assured of a safe and reliable mining operation. This is an important safety feature for any mining operation as it can help to prevent costly accidents and downtime.
Using an electronic tripping system can be the easiest way to perform a complete shutdown.
The main benefits of an electronic trip are:
- Reduced weight
- Increased reliability
- No moving parts
- No required maintenance
An electronic trip unit is more precise than an electromechanical release, meaning that it can provide a faster and more accurate response to a fault. Additionally, electronic trips can be designed to provide a variety of functions, for resetting which can reduce downtime further.
While a ground monitor is not required by law, it is highly recommended for any mining operation. Mining is a dangerous profession and any tool that can help to ensure the safety of workers should be utilized.
