Açıklama
The 590J-V2 is a lightweight field instrument which employs an indirect injection method to simulate voltage, current and burden levels in P.T. and C.T. audits to accurately determine an instrument transformer’s ratio and phase error within a utility metering or protection system. The 590J-V2 is also suited to routine workshop tests that require quick, repetitive and accurate measurements of C.T. & P.T. ratio and excitation characteristics under varying burden conditions
Performing field test measurements of Current and Potential Transformers has been made far simpler with the Model 590J-V2. This full featured product combines all of the metering CT test abilities of the popular 590G-V2 model with the additional advantage of also being able to perform both protection CT excitation tests as well as burden based inductive PT tests.
The 590J-V2 eliminates the need for additional bulky accessories usually required to perform various tests on different types of equipment, saving the operator valuable time and money. Light weight and portable, the 590J-V2 is housed in a ruggedized plastic case and is supplied with the necessary test cables and attachment accessories. It is further packaged in a foam lined transit case for safe transport.
This full featured CT and PT test instrument lowers testing costs by being simple, fool-proof and fast. It’s capabilities allow utility personnel and test technicians to pursue the very important task of testing field based instrument transformers for the detection of equipment tampering, measurement losses and faults.
