TEST-330B Three Phase Secondary Current Injection Protection Relay
Test Set For Differential relay
The TEST-330B Portable Three Phase Secondary Current Injection
Protection Relay Test Set 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 Test-330B Portable Three Phase Secondary Current Injection
Protection Relay Test Set 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, 0-10A, 0-130V accuracy 0.1%.
Its unique accuracy and reliability make the Test-330 ideal for
protection and measurement equipment manufacturers for research and
development, production and electric power company type testing.
The TEST-330B test system has the ability to be manually controlled
with GFUVE'S Relay Testing Management Software. The device with its
large, full color, high resolution, TFT LCD touch screen allows the
user to perform manual, steady-state and dynamic testing quickly
and easily using the manual test screen, as well as using built-in
preset test routines for most popular relays.
The unit can be operated either manually via the built-in Keyword,
or placed under full computer control via the GFUVE, Advanced
Visual Testing Software, or the GFUVE-software running on a PC. In
addition, with the open communication architecture, the unit can
also be used with third-party software programs such as National
Instruments LabVIEW™.
The built-in user interface, called the Smart Touch-View Interface™
(GFUVE), is Megger’s second generation of automatic /
semi-automatic manual user interface 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.
This model relay test equipment is designed with 3 currents (3*30A)
and 5 voltages (5*130V). The local software system is designed
based on Windows sytstem, which is easy and conveninent for
operation and upgrade. It supports using templates for various
relay testings, for example, G59. The relay test kit TEST-330B is
the favorable and conomical testing solution for commissioning work
in distribution grid.
