ENA Engineering Recommendation G98/NI
Type Approval and Manufacturer declaration of compliance with the requirements of G98/NI.
This form should be used when making a Type Test submission to the Energy Networks Association
(ENA).
If the Micro-generator is Fully Type Tested and already registered with the ENA Type Test Verification
Report Register, the Installation Document should include the Manufacturer’s Reference Number (the
Product ID), and this form does not need to be submitted.
Where the Micro-generator is not registered with the ENA Type Test Verification Report Register this
form needs to be completed and provided to NIE Networks, to confirm that the Micro-generator has
been tested to satisfy the requirements of this EREC G98/NI.

Manufacturer Type Test declaration. - I certify that all products supplied by the company with the above
Type Tested reference number will be manufactured and tested to ensure that they perform as stated in
this document, prior to shipment to site and that no site modifications are required to ensure that the
product meets all the requirements of EREC G98/NI.

Note that testing can be done by the Manufacturer of an individual component or by an external test
house.
Where parts of the testing are carried out by persons or organisations other than the Manufacturer then
that person or organisation shall keep copies of all test records and results supplied to them to verify that
the testing has been carried out by people with sufficient technical competency to carry out the tests.

Operating Range: This test should be carried out as specified in EN 50438 D.3.1.
Active Power shall be recorded every second. The tests will verify that the Micro-generator
can operate within the required ranges for the specified period of time.
The Interface Protection shall be disabled during the tests.
In case of a PV Micro-generator the PV primary source may be replaced by a DC source.
In case of a full converter Micro-generator (e.g. wind) the primary source and the prime
mover Inverter/rectifier may be replaced by a DC source.
In case of a DFIG Micro-generator the mechanical drive system may be replaced by a test
bench motor.
Test 1
Voltage = 85% of nominal (195.5 V)
Frequency = 47.5 Hz
Power factor = 1
Period of test 90 minutes
Test 2
Voltage = 110% of nominal (253 V).
Frequency = 51.5 Hz
Power factor = 1
Period of test 90 minutes
Test 3
Voltage = 110% of nominal (253 V).
Frequency = 52.0 Hz
Power factor = 1
Period of test 15 minutes
Remark: During the tests 1, 2 and 3 the unit does not disconnect, tests have been passed.

Power Quality – Harmonics: These tests should be carried out as specified in BS EN
61000-3-2. The chosen test should be undertaken with a fixed source of energy at two power
levels a) between 45 and 55% and b) at 100% of Registered Capacity. The test
requirements are specified in Annex A1 A.1.3.1 (Inverter connected) or Annex A2 A.2.3.1
(Synchronous).
