Three internal flux-shift trippers enable confirmation of the presence of sufficient levels of energy upon the control board for operation of pad-mounted VFI flux-shift trippers. The on-board flux-shift trippers also enable self-checking of the VFI tester prior to general control testing. Further flux-shift tripper capability enables verification of operation of the flux-shift trippers within the VFI unit under test, external to the Cooper VFI tester.


The ABB SACE PRO10/T Secondary Injection Test Set

by Protec Tech Team November 15, 2018

Circuit breakers should be tested on regular intervals to mitigate the risk of failure. A faulty breaker can cause a lot of problems if a fault condition were to occur. It is a good idea to have reliable tools that can thoroughly test the circuit breakers to avoid problems in the electrical system. One of the tools that offers complete diagnostic features for secondary injection testing of circuit breakers is the ABB PR010/T Secondary Injection Test Set.


Test SACE Circuit Breakers with the ABB PRO 10/T Secondary Injection Test Kit

by Protec Tech Team July 25, 2018

Low voltage molded case circuit breakers like the microprocessor-based SACE are often installed as protection devices for motors in industrial and commercial facilities. It is important to regularly check the condition of these devices because of the critical role that they have in protecting the electrical circuits that they are tasked with monitoring.


Why Circuit Breaker Testing is Important

by Protec Tech Team April 23, 2018

Circuit breakers are important devices that interrupt current when an electrical fault occurs. If they fail to operate properly during a fault condition, the electrical system can be at risk of being damaged.   Additionally, the mis-operation of such a device can lead to costly impacts associated with the interruption of electrical service.  Technicians should regularly test for potential problems so the circuit breakers can be verified to operate according to their intended design.  Regular maintenance practices provide the opportunity to identify and correct operational issues and ensure power system reliability.

The Siemens PTS-5 also provides a regulated DC voltage to allow functional testing of the tripping actuator.


Rent Eaton Cutler Hammer 70C1056G52 to Test Digitrip Circuit Breakers

by Protec Tech Team March 06, 2018

Circuit breakers are used in homes, office buildings, and electric facilities. These instruments are prone to break down as they gather moisture, contaminants, and dirt while in use. If not maintained regularly, ciruit breakers insulation becomes weak as a result of the heat that is created due to arc interruption. Chemicals like hydrogen sulphide or chlorine can also be major factors in the damage and corrosion of insulation as well as metal components of circuit breakers.
