What tests are conducted to verify the correct installation and functionality of the interval meter?

1. Visual inspection: The technician will visually inspect the interval meter to ensure it is properly installed and all connections are secure.

2. Functional testing: The technician will perform functional tests on the interval meter to verify that it is accurately measuring and recording energy consumption.

3. Accuracy testing: The technician will compare the readings from the interval meter with readings from a reference meter to ensure accuracy.

4. Communication testing: If the interval meter is connected to a communication network, the technician will test the communication functionality to ensure data is being transmitted correctly.

5. Load testing: The technician may conduct load testing to verify that the interval meter can accurately measure energy consumption under different load conditions.

6. Data analysis: The technician will analyze the data collected by the interval meter to ensure it is being recorded and stored correctly.

7. Calibration: The interval meter may need to be calibrated periodically to ensure accurate measurements. The technician will verify that the meter has been calibrated correctly.

8. Seal verification: The technician will check the seals on the interval meter to ensure they have not been tampered with, which could affect the accuracy of the readings.

Tests to Verify Interval Meter Installation and Functionality

1. Physical Inspection:

- Verify proper mounting and secure connections.
- Inspect for any physical damage or defects.

2. Signal Strength Verification:

- Use a signal strength meter or testing equipment to ensure a strong and stable communication signal between the interval meter and the communication hub.
- Check for obstructions or interference that may affect signal strength.

3. Meter Configuration Verification:

- Confirm that the interval meter is configured correctly with the following parameters:
- Time and date synchronization
- Current transformers (CT) and potential transformers (PT) ratios
- Demand interval settings
- Communication settings

4. Data Communication Verification:

- Verify that the interval meter is transmitting data to the communication hub or central server as expected.
- Conduct a forced meter read or data retrieval to test communication functionality.

5. Meter Accuracy Testing:

- Perform a bench test or field calibration to verify the accuracy of the interval meter readings.
- Compare the meter readings to a known reference source, such as a calibrated power analyzer or wattmeter.

6. Demand Profile Verification (if applicable):

- If the interval meter supports demand profiling, verify that the demand values are being calculated and reported correctly.
- Use load simulation or test equipment to create varying load profiles and check the accuracy of demand calculations.

7. Event Reporting Verification (if applicable):

- If the interval meter supports event reporting, verify that events (e.g., power outages, alarms) are being detected and recorded correctly.
- Test the event triggering mechanisms and verify that the event data is being transmitted to the intended destination.

8. Remote Control Functionality Verification (if applicable):

- If the interval meter supports remote control functions (e.g., load shedding), verify that these commands are being executed correctly.
- Perform remote commands to control the meter and check the corresponding responses.
