NR5210 series current transformer field calibrator

This instrument is a transformer tester developed based on a detailed analysis of the mathematical model of mutual inductors. When testing transformers, it does not require a large current power supply, a large standard transformer, or a load box. Only this instrument is needed to measure the ratio and angle errors of current transformers according to national standards. It can also measure the ratio and angle errors at any percentage between 1% and 120% of the current; it can directly measure the ratio of current transformers and voltage transformers; it can qualitatively measure the ratio and angle errors of voltage transformers; it can measure the actual secondary load of current and voltage transformers on-site, making testing particularly convenient.

Product description

Product Introduction

　　This instrument is a transformer testing instrument developed based on a detailed analysis of the mathematical model of the mutual inductor. When testing mutual inductors, it does not require a large current power supply, a large standard mutual inductor, and a load box. Only this instrument is needed to measure the ratio error and phase angle error of current transformers according to national standards. It can also measure the ratio error and phase angle error at any percentage between 1% and 120% of the current; it can directly measure the ratio of current transformers and voltage transformers; it can qualitatively measure the ratio error and phase angle error of voltage transformers; it can measure the actual secondary load of current and voltage transformers on-site, making testing particularly convenient.

Main Features

　　The instrument uses high-precision, automatically linear adjustable DC and AC power supplies; high-speed, high-reliability digital processing modules; and high-measurement accuracy, high-stability pre-measurement circuits to ensure the accuracy and high stability of the instrument's measurements. In addition, the instrument also has a user-friendly human-machine interface, prompting wiring and operation, and has the function of saving any measurement parameters and printing measurement results.
