3. Power Quality – Voltage fluctuations and Flicker
Status: P
These tests should be undertaken in accordance with EREC G98 Annex A1 A.1.3.3 (Inverter connected) or Annex A2 A.2.3.3 (Synchronous). The standard test impedance is 0.4 Ω for a single phase Micro-generating Plant (and for a two phase unit in a three phase system) and 0.24 Ω for a three phase Micro-generating Plant (and for a two phase unit in a split phase system). Please ensure that both test and standard impedance are completed on this form. If the test impedance (or the measured impedance) is different to the standard impedance, it must be normalised to the standard impedance as follows (where the Power Factor of the generation output is 0.98 or above): d max normalised value = (Standard impedance / Measured impedance) x Measured value. Where the Power Factor of the output is under 0.98 then the X to R ratio of the test impedance should be close to that of the standard impedance. The stopping test should be a trip from full load operation. The duration of these tests needs to comply with the particular requirements set out in the testing notes for the technology under test. The test date and location must be declared.

13. Re-connection timer
Status: P
Model: GW3000-XS-30
Test should prove that the reconnection sequence starts after a minimum delay of 20 s for restoration of voltage and frequency to within the stage 1 settings of Table 2. Both the time delay setting and the measured delay should be provided in this form; both should be greater than 20 s to pass. Confirmation should be provided that the Micro-generating Plant does not reconnect at the voltage and frequency settings below; a statement of “no reconnection” can be made.
| Time delay setting | Measured delay | Checks on no reconnection when voltage or frequency is brought to just outside stage 1 limits of Table 10.1. | ||||
|---|---|---|---|---|---|---|
| At 1.16 pu (266.2 V) | At 0.78 pu (180.0 V) | At 47.4 Hz | At 52.1 Hz | |||
| Confirmation that the Micro-generator does not re-connect. | 40 s | 42 s | No Reconnection | No Reconnection | No Reconnection | No Reconnection |
| Recover to normal operation range after confirmation of no connection | Yes | Yes | Yes | Yes | ||
| Confirmation that the Power Generating Module shall reconnect | Reconnection after 42 s | Reconnection after 42 s | Reconnection after 42 s | Reconnection after 42 s | ||
14. Fault level contribution
Status: P
These tests shall be carried out in accordance with EREC G98 Annex A1 A.1.3.5 (Inverter connected) and Annex A2 A.2.3.4 (Synchronous). Please complete each entry, even if the fault contribution is zero.

For machines with electro-magnetic output
| Parameter | Symbol | Value | Time after fault | Volts | Amps |
|---|---|---|---|---|---|
| Peak Short Circuit current | ip | N/A | 20ms | 56.0V | 0.8A |
| Initial Value of aperiodic current | A | N/A | 100ms | 52.4V | 3.61A |

| Parameter | Symbol | Value | Time to trip | In seconds |
|---|---|---|---|---|
| component of short circuit current* | X/R | N/A | 0.791S | |
| Reactance/Resistance Ratio of source* |
For rotating machines and linear piston machines the test should produce a 0 s – 2 s plot of the short circuit current as seen at the Micro-generator terminals.
* Values for these parameters should be provided where the short circuit duration is sufficiently long to enable interpolation of the plot.
15. Logic interface (input port)
Status: P
| Confirm that an input port is provided and can be used to reduce the Active Power output to zero | Yes |
| Provide high level description of logic interface, e.g. details in 9.4.3 such as AC or DC signal (the additional comments box below can be used) | Yes |
16. Self-Monitoring solid state switching
Status: P
No specified test requirements. Refer to EREC G98 Annex A1 A.1.3.6 (Inverter connected).
It has been verified that in the event of the solid state switching device failing to disconnect the Micro-generator, the voltage on the output side of the switching device is reduced to a value below 50 V within 0.5 s.
Confirmation: Yes
17. Cyber security
Status: P
Confirm that the Manufacturer or Installer of the Micro-generator has provided a statement describing how the Micro-generator has been designed to comply with cyber security requirements, as detailed in 9.7.
Confirmation: Yes, Manufacturer's declaration provided.
Additional comments
The inverter provides a logical interface that can be operated via an external switch or contactor to reduce the active power output to zero. Users can install the switch connected to port 7 and port 8 of the inverter and just need control the switch signal causing the switch to open or short. When the switch is closed, the inverter will operate normally. When the switch is opened, the inverter will cease to export active power within 5 seconds.
