The Test-330T three phase secondary current injection tester is the first choice for applications requiring very high accuracy more than 0.1%. This unit is not only an excellent test set for protection devices of all kinds but also a universal calibrator. It can as a ac or dc current source and voltage.
Its unique accuracy and reliability make the Test-330B ideal for protection and measurement equipment manufacturers for research and development, production and electric power company type testing.
 
The Test-330T is a multipurpose, light-weight, field portable test set capable of testing a wide variety of electro-mechanical, solid-state and microprocessor-based protective relays, motor overload relays and similar protective devices.
The unit can be operated either manually via the built-in touch-screen user interface, or placed under full computer control via the AVTS, Advanced Visual Testing Software, or the RTMS, Relay Test Management Software, running on a PC.
The built-in user interface, called the Smart Touch-View Interface™, is Megger’s second generation of automatic / semi-automatic manual user interface running the new RTMS software. It incorporates a large, easy to read Full Color high resolution, high definition, TFT LCD touch-screen display, which displays metered values such as AC and DC Amperes, AC and DC Volts, and Time in both seconds and cycles. Depending on the type of test selected, other values may be displayed, such as Phase Angle, Frequency, Ohms, Watts, VA, or Power Factor.
