The communications path between the relays is tested using suitable equipment to ensure that the path is complete and that the received signal strength is within specification.
Protection relay test equipment.
Our test equipment is ideal for each of these life cycle phases and for any environment.
The purpose of protective relay equipment is to sense fault states and trip circuit breakers.
The f6150sv has the highest output current of any test set on the market all within a single box.
This leads to additional testing requirements.
Which of the procedures described below are added to your test plan will depend on the specific project or industry specifications to be determined by the equipment owner or system engineer.
This power system simulator performs the simplest through the most complex tests.
Unit protection schemes involve relays that need to communicate with each other.
The mentor 12 incorporates the latest designs and concepts for protective relay testing based on leading edge technology.
Protective relay testing may be divided into three categories.
Megger developed the first software driven protective relay test system in 1984 and we continue to provide models ranging from computer controlled with comprehensive yet simple built in touch screen user interfaces to manually operated test sets in portable and laboratory styles for every relay testing need.
Hzjb 1a 3 phase relay test equipment.
The unique which is pc independent with easy and intuitive touch screen modular.
In order to ensure reliable operation protective relays as well as recloser controls must be tested throughout their life cycle from their initial development through production and commissioning to periodical maintenance during operation.
In a normal industrial application periodic testing should be done at least every 2 years in accordance with nfpa 70b 2016.
Acceptance testing commissioning and maintenance testing.
Every phase of voltage output is 120v and.
