Primary Injection Testing

  • Megger INGVAR | Primary Current Injection Test

    This powerful test system is designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the turns ratio of current transformers and for other applications that require high variable currents. The system consists of a control unit and a current unit. The two parts are portable, and INGVAR can be quickly assembled and connected. The control unit has many advanced features – a powerful measurement section for example, that can display turns ratio as well as time, voltage and current. A second measurement channel can be used to test an additional current or voltage. Current transformer turns ratio, impedance, power, power factor (cos ?) and phase angle are calculated and shown in the display. Current and voltage can be presented as percentages of nominal value. The fast-acting hold function freezes short-duration readings on the digital display when the voltage or contact signal arrives at the stop input, the object under test interrupts the current or injection is stopped.

  • Megger ODEN A | Primary Current Injection Test

    A powerful test system designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the transformation ratio of current transformers and for other applications that require high variable currents. Up to 8 kA can be generated. The ODEN™A system consists of a control unit together with one or two current units. All parts are portable, and ODEN A can be quickly assembled and connected. There are two versons of the current unit: S and X, S and X are identical except that X has an additional 30/60 V output.

  • Megger CSU600A / AT | Current Supply Unit

    These high-current supply units have two main fields of application. The first is to conduct primary tests on protective relays. A primary test shows whether all parts of the protection system are functioning together properly within the specified time limits under operating conditions. The second field of application involves conducting current tests on low-voltage circuit breakers and overcurrent devices.
