2.1. Operational Characteristics:
FCIE’s specified herein are supposed to facilitate fast detection of malfunctioned section by means of visual signalization in case of a malfunction in MV supply. To achieve this, the microprocessor controlled circuit in the main unit shall evaluate the fault current detected by Current Detectors and if the said current exceeds a predefined threshold value and continues for a minimum selected detection period will make the LED, failure signal lamp and auxiliary contact at the main unit active until a reset is made.
2.1.1. Current Detectors:
The Current Detectors shall have the properties of easy, faultless and quick installation. They can be mounted and demounted without the MV feed cables are being demounted. The cable between the Current Detectors and the Main Unit will be minimum 120 cm. 2.1.2. Current setting (setting of threshold values):
- Phase-to-Overcurrent figures: Can be adjustable starting from 200* Amperes up to minimum
600 amperes (with at least three steps). - Excess zero component current (3Io) figures: Can be adjustable starting from 20 Amperes to
*: 225 and 250 Amperes are also acceptable as initial steps. 2.1.3. Failure Detection Period:
It is the period necessary for the main unit to identify an excess of fault current beyond the threshold value as a “failure”. Failure Detection Period should be adjustable from 50 ms to 300 ms (with at least 4 steps). 2.1.4. Recovery to Normal Operation (Reset):
The “Recovery to Normal Operation (Reset)” operation shall be executed in four different ways, which are: a) Reset by re-energizing: The system shall automatically reset approximately 3 seconds after re-
energizing following the remedy of the failure is actualized at the Feeder the Current Detector is connected. b) Reset by time setting: The system should automatically reset itself within 2 or 4 hours at
maximum (which should be adjustable) even if the failure is still active. c) Manual reset: It shall be possible to reset manually via a button on the instrument
d) Reset by Remote Control: If specified at the Material List, the FCIE reset shall be possible
through digital entry remotely (from Control and Monitoring Centre). 2.1.5. Failure Signal Lamp:
The Failure Signal Lamp will be composed from a lamp and enclosure and connected to the Main Unit with a cable. Unless a reset is not made the Fault Indication LED in the Main Unit and the lamp inside the Failure Indication Enclosure shall blink synchronously (with the same period). Blinking period shall increase depending on the duration of failure. Example:
Like, blinking per 2 second for the first 2 hours, blinking per 3 seconds for 2 to 3 hours, and blinking per 4 seconds for 3 to 4 hours. The flashing light of the Failure Signal Lamp shall be seen easily from a distance of at least 20 meters. The cable to be used for the connection between the Main Unit and the Failure Signal Lamp will be at least 10 meters. 2.1.6. Parameter Settings:
The Parameter Settings will be possible to be made easily from the Main Unit. 2.1.7. Insulation Characteristics:
Test voltage with network frequency (50 Hz-1 minute) 2.2. Structural Properties
2.2.1. Displays
FCIE will comprise minimum the following displays on it. These are: A Test Button to indicate whether the FCID is on or not.
A LED Display to indicate whether there is a failure or not.
2.2.2. Auxiliary Contact
There will be at least 1 (one) Auxiliary Contact normally open (NO) to be used for remote control and monitoring. Current flow rating of the contact will be at least 0.5 Amperes at 60 V DC. 2.2.3. Protection Level
- Main Unit Enclosure: Components of the main unit shall be located in an internal enclosure. The protection level of the Enclosure will be minimum IP23 as per TS 3033 EN 60259 for dust, solid objects and water and IK-07 for mechanical impacts. - Failure Signal Lamp Enclosure: The protection level of the Failure Signal Lamp Enclosure will be minimum IP54 as per TS 3033 EN 60259 for dust, solid objects and water and IK-07 for mechanical impacts. 2.3. Power Supply
FCIE (including all its hardware) will not require an external power supply and will be fed by a lithium cell located inside the instrument. The life of the lithium cell will not be less than 400 hours with the lowest signal period for 7 (seven) years. 3. TESTS:
Tests shall be performed in compliance with relevant standards. 3.1. Type Tests:
