An Innovative Advancement in CT Testing

........................................

OVERVIEW

The Radian RD-BR1 Burden & Ratio Analysis Module is an innovative advancement in current transformer (CT) testing. When used with Radian’s RD-2x or RD-3x Dytronic Standards this accessory provides several benefits over other testing methods. The RD-BR1 allows testing without interruption to the customer’s service and the design features single cycle burden insertion with simultaneous CT ratio and phase error. The module’s unique design allows all ANSI values of 0.1, 0.5, 1.0, 2.0, 4.0 and 8.0 Ohms to be inserted with virtually no magnetizing effect on the CT. When testing with the RD-BR1 the user need not be concerned with overheating. An onboard temperature controlled fan keeps the module running cool and trouble free.

RD-BR1 CT Testing

Testing with the RD-BR1 can be performed using any of the multiple burden resistors available. Utilizing Radian’s unique solid state technology users can select multiple burdens or the complete sequence can be performed. Each burden is inserted and removed in an one line cycle, allowing the CT to be tested without adding any residual magnetization of the CT. Using this measurement technique minimizes any uncertainty of measurement caused by fluctuation of load. The measurements of current with and without burden allow the percent change to be automatically calculated.

Reduce lost revenue with the module’s CT Ratio feature allowing the technician to verify CT nameplate information without removing the CT from service. Technician time spent at each site is also reduced with the addition of the CT Phase Error function allowing the detection of defective installations while testing the CT ratio.

RD-BR1 prevents unnecessarily changing of a good CT resulting in saved time and money. This is accomplished by performing a quick CT demagnetization on a CT that is saturated. CT demagnetization can effortlessly be performed at the end of each performance test.

The RD-BR1 provides unsurpassed user safety and is considered the safest CT Burden & Ratio Tester available. The module prevents user harm through an automatic system continuity check that is preformed before opening the secondary of the CT. If an open loop is detected the RD-BR1 will automatically close the loop. In addition, testing of the internal burden resistors is done to verify operation before adding them into the secondary loop.

Data collection is easily saved and collected during the test. Test configurations and results can then effortlessly be stored or downloaded. Quick and simple test reports are automatically generated at the end of each test. This data can be easily viewed or exported.

The Radian RD-BR1 Burden & Ratio Analysis Module is truly an addition you should not be without when performing a CT test. The RD-BR1 is another in a highly respected line of Radian products providing unparalleled measurement accuracy. With the safety and multiple user functionality benefits the RD-BR1 provides it will soon be realized that the module is an efficient addition to your Radian RD-2x or RD-3x Dytronic Standards.
