CSP Technology

 

Complete self-protected technology for high performance distribution transformers

 

CSP is a protection system for distribution transformers. The CSP protection system protects the transformer from lightning, secondary faults, severe overloads and provides visual warning of abnormal loading conditions.CSP technology allows transformer manufactures to build high performance distribution transformers which mitigate the operation and maintenance problems associated with conventional transformers.

 

CSP design provides maximum protection against transformer failure and disruptive outages. It also protects you from extra costs of more complicated installation, unnecessary equipment and power downtime.

 

RockWell CSP protection system

 

Rockwell transformer CO.,LTD manufactures several components, in order to create the CSP transformer. These components when applied to the transformer during its manufacturing process, provide multiple layers of protection.

High voltage fuse

 

Acts as over current protection by isolating the faulty transformer from the network. it is mounted inside of the transformer and it is connected between the incoming high voltage lead from the bushing and the high voltage line lead from the transformer primary winding.

 

Low voltage (secondary) circuit breaker

 

Provides secondary fault and overload protection. the circuit breaker is mounted inside of the transformer and it is connected between the secondary winding and secondary bushing, such that the current flows through the circuit breaker.

 

Overload indicator

 

Provides visual indication of abnormal loading conditions. the signal light is electrically connected to the signal light sensing circuit within the transformer.

 

CSP advantages

 

Lower installed cost

 

Less time for installation

 

Easier and simpler installation

 

Safer operation

 

More reliable service

 

Automatic load management

 

Lower cost of operation

 

Lower maintenance cost and time

 

Better aesthetics

 

Oil immersed low voltage(secondary)circuit breaker

 

The low voltage circuit breaker is the central component of CSP technology. It is this circuit breaker which provides the entire over current protection to the transformer. Circuit breaker protects the transformer in the following scenarios:

 

Thermal protection:

 

To increase the longevity of the transformer the circuit breaker will trip once the oil in the transformer reaches a pre-determined temperature level.

 

Overloading:

 

Similar to thermal protection, the circuit breaker will protect the transformer from damaging overloading conditions for a sustained period of time.

 

Secondary fault (short circuit):

 

The circuit breaker will respond to secondary faults external to the transformer by tripping open, and in most cases, this action will prevent any thermal damage occurring to the transformer.

 

RockWell circuit breaker advantages

 

Conforms to IEC standards IEC-60947-2 specifications.

 

High quality components

 

Available in 1-Pole,2-Pole and 3-Pole variations for single phase and three phase transformer. Current rating up to 270Amps.

 

Thermal protection settings customized as per customer requirements.

 

Signal light to provide early warning of overload/high oil temperatures.

 

Operating handle allows quick reset.

 

Optional features

 

Magnetic trip

 

Magnetic trip element increases the opening speed of the circuit breaker under high fault current conditions. this increased opening speed permits the circuit breaker to interrupt larger values of fault currents.

 

Emergency control

 

Emergency control allows the power utility to immediately restore service in an emergency by closing the circuit breaker even when the preset overloading limit is reached.

 

Breaker on bracket (BOB)

 

Breaker on Bracket design allows simple and fast installation of the circuit breaker. significantly reduces any issues borne out of incorrect installation of the circuit breaker.
