Abstract :
A number of unfortunate experiences in the past, resulting in the loss of lives, have made many persons conscious of the hazards which can exist on the high-voltage systems serving strip-mining operations. Several years ago a system design employing the neutral grounding resistor was adopted. This has greatly minimized the number of shock accidents caused by equipment and cable failures.
