Alert systems indicate removal of one or more protected portions of electrical grounding assemblies. An alert system can include a signal transmitter, a signal receiver, an alert device, and a communication cable. The signal transmitter can transmit a signal to be received by the signal receiver. The alert device can be coupled to the signal receiver, such that the alert device is activated when the signal is not received. A non-metallic communication cable can propagate the signal from the signal transmitter to signal receiver. The communication cable can be bound to a protected portion of the grounding assembly, such that disturbance of the protected portion can damage the communication cable. Because damage to the communication cable can cause an interruption in the signal, such damage can result in activation of the alert device. Accordingly, disturbance of the protected portion of the grounding assembly can activate the alert device.
