Who May Sign the Test Report?

The main regulatory defect is that the final test report was issued by an ECT over his own signature, with no supervising ECE or PECE identified as responsible. ECTs may perform routine tests under supervision, but the report that certifies results must be under the direction and review of the engineer responsible for the test. Writing 'for the Resident Engineer' does not transfer responsibility and is misleading because no named engineer reviewed the work. 'Back-signing' after the report has already gone to the utility would be a false attestation unless the PECE actually reviews the data and accepts responsibility. The technical defects are also serious. A 0.6% ratio deviation may exceed the applicable tolerance; transformer ratio tolerance is commonly ±0.5% of the declared ratio under the applicable standard, so the ECT's 'pass' must be checked against the correct acceptance criterion. The insulation-resistance value of 1.1 GΩ at 30 °C must be temperature-corrected and compared with the specified minimum, not merely marked pass. The report should also identify the instrument calibration status, test voltage, and test conditions.

Before signing, the PECE must review the raw data sheets, the test method, the instrument calibration certificates, the test conditions, the nameplate data, and the applicable acceptance criteria. He must confirm that the ECT was competent and supervised, and that the recorded values are complete and internally consistent. If the data are insufficient or the ratio result is outside tolerance, he must not certify a pass. He should authorize re-testing or issue a factual report that states the measured values, the applicable limits, and any nonconformance. If the Monday deadline cannot be met with a truthful report, he should tell the client and the utility in writing that a preliminary data report is available but that certification is pending resolution of the nonconformance. He should not sign a 'pass' report to meet the energization schedule. If the transformer is nonconforming, the proper outcome is a report that supports engineering disposition, not a false clearance.

The laboratory should adopt a written supervision plan that names the supervising ECE or PECE for each test category and states who may release reports. Only authorized signatories should appear on the letterhead, and every report should show the name and PRC registration number of the responsible engineer. ECT-prepared data should be reviewed before a report is released, and the report should state that the tests were performed under the supervision of the named engineer. The laboratory should keep raw data, calibration records, and review checklists, and it should prohibit 'back-signing' after release. It should also define what happens when the supervising engineer is absent: either reschedule the test or have another qualified engineer review and sign. Finally, acceptance criteria should come from the applicable standard or the client's approved specification, not from an informal 'client criteria' note, and any deviation should be escalated before a pass or fail is recorded.
