“…In their research, ACE is defined as coupling error due to coupling between a current clamp meter and a current coil when calibrating a current clamp meter with a current coil. While PCE is a new error parameter which they proposed to be taken into account as an uncertainty source in calibration of power clamp meters (Olencki & Mróz, 2017).…”

This paper presents a traceable measurement method developed in the Laboratory of National Measurement Standards for Electricity and Time (NMS Lab for Electricity and Time) -National Standardization Agency of Indonesia for calibrating current coil in order to obtain correction and uncertainty estimation of the current coil windings number (N). Current coils as objects of this research were 10-turn and 50-turn current coil. Calibration was performed using standard multiproduct calibrator (MPC) and two auxiliary devices, current coil F-5500 and clamp meter F-337. Correction and uncertainty values of N current coil were evaluated for DC and AC supplied current using formulation developed based on principle of current division between current coil output and supplied current from MPC. Based on evaluation result analysis, the expanded uncertainties of this method span from 0.47% to 1.0% (when supplied by DC current) and from 0.57% to 1.1% (when supplied by AC current) for 10-turn current coil, and span from 0.44% to 0.65% (when supplied by DC current) and from 0.54% to 0.96% (when supplied by AC current) for 50-turn current coil. Moreover, it also showed that the largest uncertainty component came from current coil F-5500. Meanwhile, the largest correction for 10-turn current coil was obtained 1.2% at 10 A DC, and for 50-turn current coil was obtained -0.47% at 700 A AC. Verification of the calibration and evaluation methods had also been carried out and it indicated that the calibration and analysis methods developed can be used to examine the performance of the current coil. AbstrakPaper ini memaparkan tentang metode pengukuran tertelusur yang dikembangkan di Laboratorium Standar Nasional Satuan Ukuran Kelistrikan dan Waktu (Lab SNSU Kelistrikan dan Waktu) Badan Standardisasi Nasional (BSN) untuk mengkalibrasi current coil guna mendapatkan koreksi dan estimasi ketidakpastian jumlah lilitan (N) current coil. Current coil yang menjadi objek penelitian ini adalah current coil 10 lilitan dan 50 lilitan. Kalibrasi dilakukan dengan menggunakan standar multiproduct calibrator (MPC) dan dua perangkat bantu, yaitu current coil F-5500 dan clamp meter F-337. Nilai koreksi dan ketidakpastian N current coil dievaluasi untuk arus suplai DC dan AC dengan formulasi yang dikembangkan berdasarkan prinsip pembagian arus antara arus keluaran currrent coil dengan arus suplai MPC. Berdasarkan analisis hasil evaluasi, ketidakpastian bentangan yang didapatkan menggunakan metode ini terentang dari 0,47% hingga 1,0% (ketika disuplai oleh arus DC) dan dari 0,57% hingga 1,1% (ketika disuplai oleh arus AC) untuk current coil 10 lilitan, dan terentang dari 0,44% hingga 0,65% (ketika disuplai oleh arus DC) dan dari 0,54% hingga 0,96% (ketika disuplai oleh arus AC) untuk current coil 50 lilitan. Selain itu, hasil analisa juga menunjukkan bahwa komponen ketidakpastian terbesar berasal dari current coil F-5500. Sementara itu, koreksi terbesar untuk current coil 10 lilitan didapatkan sebesar 1,2% pada 10 A DC, dan untuk current coil 50 lilitan adalah...
