eneida DeepGrid EdgeSense - Model EWS DTVI-g - Smart Sensor
EWS DTVI can provide all relevant electrical parameters from the distribution network. All the inputs are sampled synchronously without gaps at 8kHz sampling rate. The refresh rate for voltage and current is half-cycle (10ms @ 50 Hz) and one second for all other parameters. Data is then aggregated and published at the configured periods. The Table below synthesises all the data that can be provided.
EWS DTVI has a Bluetooth module that simplifies commissioning of each unit by the user seamlessly, guiding the user with all relevant information across the installation process, such as:
- Feeder name;
- Fuse / Circuit breaker nominal current;
- Transformer phase rotation and nominal power;
- Site ID and location.
The Mobile App also allows the user to validate the installation by running an installation check.
Moreover, this Bluetooth module enables communication with other sensors inside the substation, such as:
- Flood level indicator;
- Ambient temperature and humidity;
- Transformer temperature;
- Intrusion (all of these devices are available from Eneida.IO portfolio).
EWS DTVI is primarily self-powered by the voltage signals and has a small energy backup in order to alert the power failure. Additionally, it can be powered by an external power supply if the substation has a secure DC power supply. Optionally, if the substation does not have a secure voltage and should EWS DTVI be required to continue working after a voltage interruption or any another abnormal event, a power backup module composed of Supercapacitors can be connected to EWS DTVI.
EWS DTVI has the capability to remotely upgrade its firmware over the air or Ethernet port. It can therefore be configured remotely and benefit from data logger functions (2 configurations available: time between data aggregation and time between communications)
EWS DTVI allows DSOs the ability to run specific Low Voltage Applications (LV Apps). These Apps can be remotely activated for a period of time or run indefinitely. Furthermore, all the Apps can run simultaneously. The Apps available from Eneida include:
- Current Fault Detection & Location (Incl. Fault Level Indicator),
- Dead Section/ MV Fault Location,
- Network Power Quality (according to IEC 61000-4-30, class S),
- Grip Topology Mapping,
- Energy Balance (Technical & Non-Technical Losses Monitoring and Location),
- WFC - Wave Form Capture capability.
