Electronic and Automatic Primary Injection Test System (eKAM)

Açıklama

eKAM test system includes two portable units: one control unit
with a large graphical display that adjusts the AC voltage output
(up to 220 V) and one current unit (up to 2000, 3000, 5000A).
BUX 2000 (2000 A) – BUX 3000 (3000 A) – BUX 5000 (5000 A):
one or more BUX current unit can be connected to eKAM (not
simultaneously), they can be ordered separately when the order
is placed or at a later moment.
With the control knob and the LCD display, it is possible to enter
the MENU mode, that allows to set many functions, making
eKAM a very powerful testing device, with manual and automatic
testing capabilities and with the possibility to transfer test
results to a PC via ETHERNET or Pen Drive.
The TDMS software, which comes with the test set, allows to
download, display and analyze test results obtained in local
mode. Remote maintenance and diagnostic of the instrument
are available via Ethernet. TDMS software operates with all Windows
® versions. The ease of operation has been the first goal of
eKAM. This is why the LCD display is so large and the dialogue in
the MENU mode is made easy.
eKAM includes three measurement inputs:

. DC voltage (10 V DC).
. AC voltage:
.. High range (300 V AC)
.. Medium range (10 V AC)
.. Low range (3 V AC)
. Current (10 A AC or DC).

All these inputs are independent among them (unless 3V and
300V) and allow the measurement of CT outputs or of another
source. In addition, a digital input (up to 300 V) is available: it
can measure the timing of a wet or dry contact. The instrument
is housed in a transportable aluminium box, which is provided
with a cover and handles for ease of transportation. A transport
case can also be supplied upon request.

GENERATOR OUTPUTThe internal generator has one high power - AC voltage output, notinsulated from the mains. The adjustment is performed by the localThe generated frequency can be userdefined or synchronized to thesupply frequency (with optional power line synchronizer). The followingspecification applies to the output.

The test set allows testing protection relays. The test current or voltage can be ramped or stepped. As the output changes, a timer is started; the timer stops as the Digital input senses that the relay has tripped or the output cut is cut. Characteristics of the Digitalinput:

The input may be selected as Normal Open, NormalClosed
The timer can start from an analog input ( current orvoltage)
The timer can start and stop at the changing of the digital input, both dry or wetcontact
Type of input: either dry or under voltage. Maximum input: 300 V AC orDC
Voltage thresholds: 5 V, 24 V, 48 V or > 80V
Timer resolution: 1ms

Phase angle measurementThe test set measures the phase angle between the two AC selected parameters which are used during the test.
