These values provide information that may be useful for debugging an EGD network. The EGD signature and packet size
for the slow EGD exchanges are displayed.
6.2.19 TELEPROTECTION CHANNEL TESTS
PATH: ACTUAL VALUES  STATUS  TELEPROT CH TESTS
The status information for two channels is shown here.
• CHANNEL 1 STATUS: This represents the receiver status of each channel. If the value is “OK”, teleprotection is
enabled and data is being received from the remote terminal; If the value is “FAIL”, teleprotection enabled and data is
not being received from the remote terminal. If “n/a”, teleprotection is disabled.
• CHANNEL 1 LOST PACKETS: Data is transmitted to the remote terminals in data packets at a rate of two packets per
cycle. The number of lost packets represents data packets lost in transmission; this count can be reset to 0 through the
COMMANDS  CLEAR RECORDS menu.
• VALIDITY OF CHANNEL CONFIGURATION: This value displays the current state of the communications channel
identification check, and hence validity. If a remote relay ID does not match the programmed ID at the local relay, the
“FAIL” message will be displayed. The “N/A” value appears if the local relay ID is set to a default value of “0”, the chan-
nel is failed, or if the teleprotection inputs/outputs are not enabled.
