Atec Megger-MPRT8445 - Manual (Page 2)

Here’s how easy it is
From the Preset Menu Screen, shown below, the user
simply selects the type of relay to be tested. Built-in test
files are for a wide variety of protective relays, including
Overcurrent, Differential, etc., see following figure.
MPRT
Megger Protective Relay Test System
2
Includes Three Communication Ports – More built-in
flexibility with a protocol choice of IEEE488, RS232 or
Ethernet for high-speed download capability and upgrades
via the internet.
User Specified Configuration – Every system is made to
order based on each customer’s testing requirements and
budget, with an easy and flexible upgrade path.
Output Capabilities for Worldwide Use – Even more
built-in flexibility allows the user to choose from:
I VI-Gen amplifiers rated at 30A @ 200 VA and
convertible amplifiers rated at 300V or 5A @ 150 VA.
I VI-Gen amplifiers rated at 15A @ 200 VA and
convertible amplifiers rated at 150V or 5A @ 150 VA.
THE TOUCHVIEW INTERFACE (TVI)
Finally...an easier way to perform manual and semi-
automatic relay testing. It’s all done via a unique hand
held controller called the TouchView Interface (TVI). The
most significant feature of the TVI is its ability to provide
the user with a very simple way to manually test even the
most complex relays manufactured today.
Manual operation is simplified through the use of a
built-in computer operating system and the TouchView
Interface, with a large color LCD touch-screen. The TVI
eliminates the need for a computer when testing virtually
all types of relays. Menu screens and function buttons are
provided to quickly and easily select the desired test
function.
Preset Relay Menu Screen
Overcurrent Relay Settings Screen
As an example, touch the ‘Over Current’ button. An
Overcurrent Test Menu Screen, shown below, will be
displayed showing all necessary functions needed to test
that particular type of relay. Next, the user inputs the relay
setting values that will be used to conduct the tests, such
as Relay Tap value and Time Dial value. These values are
used when conducting the pickup and timing tests.
To make it even better, the TVI has both IEEE and IEC
time curve algorithms built-in. By entering the appropriate
values in the setting screen, when the timing test is
conducted, the test results will be automatically compared
to the theoretical values from the time curve that was
selected.
