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.

What is a Secondary Injection Test Kit

by Protec Tech Team May 21, 2018

The protective devices that are used for the oversight and operational decision making in low voltage circuit breakers (LVCBs) are are often simply referred to as a Solid-State Trip device (SST).  They are essentially protective relays that are frequently an integrated part of a low voltage circuit breaker and monitor the primary current path of the circuit breaker.  In normal operation, these solid-state trip devices will sense changes in the primary current path and make the decision to open the circuit based on the magnitude and duration of the fluctuation.

Choosing an ABB Secondary Injection Test Kit Suitable for Your Needs

by Protec Tech Team April 23, 2018

 Secondary injection testing is a diagnostic method of determining if a secondary protective device will respond as  expected in both normal and faulted conditions. This method of testing is conducted by injecting signals directly into the trip unit that controls that operation of the circuit breaker to which it is connected.

Since this type of operational testing is performed by injecting secondary signals into the device instead of using primary current levels, it is generally considered to be a safer method of verifying the proper operation of a circuit breaker. This method of testing can be performed on circuit breakers as a part of commissioning or preventive maintenance.

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.

Micrologic, NT and STR Trip Units Reliably Tested with Square D S33595

by Protec Tech Team November 13, 2017

When it’s necessary to test circuit breakers and protective relay systems, a secondary injection test set is the main piece of electrical test equipment companies utilize. Secondary injection testing differs from the standard primary injection testing method in that there is no current flowing and contacts remain closed during the testing process.

Rent Secondary or Primary Current Injection Test Sets, the Best Option

by Protec Tech Team July 06, 2017

Secondary current injection testing is performed on solid-state trip units using a specially designed power supply unit. However, the secondary injection method only tests the solid-state trip unit, and does not test the current sensors, wiring, or the breaker current handling components.
