16: Insulation Resistance (Megger) Testing

16.1 Scope

The Contractor shall perform insulation resistance testing, commonly referred to as Megger testing, on the electrical distribution systems and major electrical machinery aboard the R/V Medeia. The purpose of this work item is to evaluate the condition of electrical insulation throughout the vessel and identify any degraded or failed insulation that presents a risk of ground fault, shock hazard, equipment damage, or fire. Testing shall be conducted on all accessible shore-power, main distribution, branch circuit, and machinery wiring, including motors and generators, as identified in consultation with the Owner Representative.

Standards:

IEEE 43 – Recommended Practice for Testing Insulation Resistance of Electric Machinery NFPA 70B – Recommended Practice for Electrical Equipment Maintenance ABYC E-11 – AC and DC Electrical Systems on Boats (as applicable to commercial vessels)

Prior Test Records:

Reference 16-1 Medeia Megger Report 2023 (Baseline insulation resistance survey covering panelboards: Void Room/Work Shop, P2 Engine Room, P1 Engine Room, Galley/Main Deck, Wheelhouse Panel, Misc Loads, and Generators and Shore Power. Contractor shall reference this report when interpreting 2027 test results and shall note any circuits or equipment showing measurable degradation relative to 2023 baseline values.)

16.3 Requirements

16.3.1 – Technician Qualifications All insulation resistance testing shall be performed by a qualified marine electrician or certified electrical technician with documented experience conducting insulation resistance surveys on commercial or research vessels. Prior to commencing work, the Contractor shall provide the Owner Representative with documentation of the assigned technician's qualifications upon request.

16.3.2 – Test Equipment The Contractor shall supply all test equipment necessary to perform insulation resistance measurements across the range of voltages present aboard the vessel.

Test voltage applied to each circuit or component shall be appropriate to the rated system voltage, as follows: circuits rated 120/240V shall be tested at a minimum of 500 VDC; circuits rated 440V or higher shall be tested at a minimum of 1,000 VDC.

All equipment shall be calibrated and in good working order. The Contractor shall provide calibration records upon request.

16.3.3 – Scope of Testing At a minimum, the Contractor shall perform insulation resistance tests on the following systems and equipment. ADF&G Representative may direct the Contractor to expand or reduce the testing scope based on vessel condition or access constraints observed during the work period:

• Shore power inlet and main switchboard distribution circuits

• Main and emergency generator windings and output circuits

• All AC branch circuits serving machinery spaces, accommodations, and work decks

• DC distribution circuits, including battery banks and charging circuits

• Main engine starting motors and associated wiring harnesses

• Electric motor windings for all bilge pumps, fire pumps, wash-down pumps, and hydraulic power unit motors

• Winch and crane motor circuits
