Current Limiting Protection (CLiP)

Current Limiting Protection (CLiP)

The Importance Of Current Limiting

The CLiP current limiting protector has provided unparalleled system protection in Australia and around the world, for over 20 years. It offers the advantages of current limitation for systems rated to 38kV with high continuous current ratings up to 5000A. Fault interruption beyond 300kA rms symmetrical at 15.5kV has been achieved. The CLiP is an electronically sensed and triggered, commutating form of current limiter, sometimes referred to generically as an Is-Limiter, where a continuous copper bus bar path carries the continuous current. This path is opened under overcurrent conditions to introduce a parallel mounted current limiting fuse which interrupts the fault.

At CSE Uniserve, we have been delivering first-rate electrical power management solutions to the biggest companies working in areas like mining, oil and gas, refining, water treatment and transportation for forty years. To date, we are considered one of the foremost authorities in industrial engineering and we continue to serve the needs of our clients by providing first-class products, maintenance and training to keep their facilities running efficiently and safely. We are committed to the wellbeing, health and safety of everyone. We operate under third party accredited HSEQ Management System.

To this end, we can supply your organisation with appropriate and effective current limiting protection technology like the CLiP from G&W.

Are You In The Market For Modern Current Limiting Protection?

The CLiP is often used to protect against underrated switchgear. It is installed indoor or outdoors, in vertical or horizontal positions and can be deployed rapidly to suit operations with recently identified issues that require a reliable solution, fast. A CLiP can enhance personnel protection or limit damage to critical systems such as the power grids, equipment like generators or large motors and most importantly, switchgear and substations.

The CLiP is also ideal arc flash protection.  By halting energy supply within the first cycle, the let-through energy from a CLiP is typically less than 1% compared to a breaker. The CLiP is a critical part of planning for personnel protection in extreme environments like refineries, oil and gas production and other highly explosive or dangerous industries. Instead of trying to cope with fault energy by traditional techniques, it is far more effective to use the CLiP to simply cut off the fault energy should a situation occur. Typical applications include the bypassing of reactors to eliminate reactor power losses and regulation problems, particularly those related to starting large motors.

The Versatility of A CLiP

Upon sensing an overcurrent condition, a CLiP inserts the reactor back into the circuit in a current limiting fashion. The CLiP is commonly applied in a bus tie position, which enables closure of the tiebreaker to better balance system sources and loads. It often bypasses a tie position reactor. Bus tie applications account for more than sixty percent of CLiP applications. Cogeneration and grid connection protection is an area of substantial usage. The CLiP is used to eliminate the additional contribution of a cogenerator to a system; thereby maintaining fault currents within the equipment ratings. This also applies to wind turbine usage. Conversely, it can be used to protect the cogenerator itself.
