Abstract
Embodiments of the invention provide for a system and method for operating a hydraulic tool near high-voltage components. The hydraulic tool may be connected to couplers and receiving hydraulic fluid from a pump and returning the hydraulic fluid to a tank in an open center system or returning the hydraulic fluid to a tank in a closed center system. In the event of a loss in pressure the valves in the system change state stopping the flow of hydraulic fluid to the hydraulic tool without the use of electrical components.
