Features: To standardize the on-site periodic calibration of electrical measurement instruments, strictly implement relevant regulations and requirements, and ensure that calibration personnel can complete their tasks safely and efficiently in large-scale on-site calibration work, North China Power Grid Co., Ltd. has developed the On-site Operation Guide for Electrical Measurement Instruments and organized relevant professionals for careful review. This operation guide is applicable to on-site calibration tasks of electrical measurement instruments, including:
On-site testing of current transformers for energy metering;
On-site testing of voltage transformers for energy metering;
On-site testing of voltage drop in the secondary circuit of voltage transformers;
On-site testing of energy meters;
On-site testing of voltmeters and ammeters;
On-site testing of three-phase power meter errors;
On-site testing of single-phase power factor meters, frequency meters, and on-site testing of single-phase power frequency phase;
On-site testing of synchronizing devices;
On-site testing of DC digital instruments;
On-site testing of energy transmitters;
On-site testing of AC sampling devices.
This operation guide can serve as a reference for on-site personnel during operations and also as a training reference for personnel before operations.
