About the product

The MS5200 smart grid medium voltage sensor complements distribution management systems by providing on-line information about faults and grid operations. It includes the ability to connect to ground to enable you to perform a direct voltage measurement instead of calculating the voltage from measurement of the electric field.

The 0.5 % accuracy of the voltage measurements makes the MS5200 the ideal choice for applications such as Volt/VAR optimisation, medium voltage power metering, and the detection of technical and non-technical losses.

The MS5200 is a modular system designed to operate in power grids with solid grounding and any other type of earthing, including Petersen coil compensation. It works by deploying sensors in a radio network, which then automatically create a secured mesh network between themselves. When required, additional routers and sensors automatically and effortlessly connect to the network and report abnormal events such as surges and current/voltage drops. These can be accessed at any time using the MetryView software.

The MS5200 is available in two versions:

MS5200-SU: Sensor unit with radio communications. The unit can be connected to MS5000-GS sensor/gateway or to other MS5200/MS5000 sensors units or to MS3010 gateway or routers
MS5200-GS: Sensor unit with integrated cellular gateway

Troubleshooting

The GS sensor is not connecting to the server after SIM insertion. (GS sensor does not blink 3 times)

Connect the GS sensor to the Bloader SW, which was provided by MGA, and confirm the APN code (APN is provided by the SIM provider. Note that some SIM cards will also require a user and password credentials, which should be provided by the SIM provider.)
Confirm with the SIM provider that the SIM card is active
Ensure sufficient cellular coverage at the installation site
Contact MGA support

One of the SU sensors is blinking only twice every 5 sec

This will indicate that the SU sensor is not yet synchronised with the GS sensor, and still trying to connect
Check the sensor battery (the first blinks after turn-on of the sensor will indicate the sensor’s battery status:
- 1 blink: battery level very low
- 2 blinks: medium battery level
- 3 blinks: battery is full
Charge the battery using a USB cable if necessary
Check set and sensor’s ID number and make sure sensors were not mixed with other sets
Contact MGA support

Voltage measurements are inaccurate when using MS5200

Ensure that the MS5200 divider and grounding hook are properly installed as described in the ‘MS5000 User Guide’, section 7.9.
Contact MGA support

The sensor set is shown on the Metryview diagram, but it does not display any data

Confirm the sensor is properly registered and listed (sensor IDs) in the configuration tab on Metryview
Sensor connection loss can be related to the low battery of the sensor. In this case, you might need to relocate the sensors to a different line with sufficient current for charging:
- open the ‘Daily Graph’ tab and check the sensor's last connection to Metryview
- once located, open the ‘Battery and Charging Status’ graph and check the battery voltage status and line current while it was last connected.
If the battery voltage and current were sufficient when last seen, check that the SIM card data package is still valid by contacting your SIM provider.
