Data Logger - GE L60 Instruction Manual

5.2 PRODUCT SETUP
All eight CT/VT module channels are stored in the oscillography file. The CT/VT module channels are named as follows:
<slot_letter><terminal_number>—<I or V><phase A, B, or C, or 4th input>
The fourth current input in a bank is called IG, and the fourth voltage input in a bank is called VX. For example, F2-IB desig-
nates the IB signal on Terminal 2 of the CT/VT module in slot F. If there are no CT/VT modules and Analog Input modules,
no analog traces will appear in the file; only the digital traces will appear.

DATA LOGGER

5
The data logger samples and records up to 16 analog parameters at a user-defined sampling rate. This recorded data may
be downloaded to EnerVista UR Setup and displayed with parameters on the vertical axis and time on the horizontal axis.
All data is stored in non-volatile memory, meaning that the information is retained when power to the relay is lost.
For a fixed sampling rate, the data logger can be configured with a few channels over a long period or a larger number of
channels for a shorter period. The relay automatically partitions the available memory between the channels in use. Exam-
ple storage capacities for a system frequency of 60 Hz are shown in the following table.
