With the ever-increasing demand for electrical energy, electrical systems have been forced to expand and grow. Increased substation capacity, on site and distributed generation all contribute to subsequent increases in available fault currents imposed on equipment. This short-circuit current may exceed the thermal, mechanical and interrupt capability of the system, potentially causing a catastrophic failure.
The CLiP-LV is an electronically sensed and triggered, commutating form of current limiter, sometimes referred to generically as an Is-Limiter. A built-in current transformer (CT) provides real time current values to the internal electronics. The CLiP-LV has a field adjustable instantaneous pickup setting referred to as the trigger level. If the current exceeds the user-defined trigger level, a signal is sent by the firing logic to interrupt the current. A continuous copper busbar path carries the continuous current, which is opened during overcurrent conditions, while a parallel connected current-limiting fuse interrupts the fault. The CLiP-LV’s unique ability provides high continuous current ratings with current limitation and ultra-high-speed operation in one package. This makes it an economical solution to protect against short-circuit interruptions without having to add new equipment.
Arc Flash Mitigation
An arc flash typically occurs when fault current travels through air from one conductor to another or to ground. The energy generated by the flash can cause significant equipment damage and/or serious injury. CLiP-LV is the best method to minimize or eliminate the problem by reducing the fault current and time duration. In addition to Personal Protection Equipment (PPE), the CLiP-LV provides additional protection creating a much safer overall environment.
The design, quality and operation of G&W’s CLiP-LV has been certified by this globally recognized agency and now complies with Standard(s) for Safety: UL 3801, Outline of Investigation for Fault Limiters. This product can now be offered to industrial customers who want a lower cost alternative to replacing aging equipment. CLiP-LV UL rating gives our customers an added layer of certainty that our product has been tested and is safe to use in their configurations
