Tester for measuring the ratio error of current ★★★ Instruments for distribution boards, control panels, distribution panels, and panels.
The high-voltage MOF is used to measure the ratio error between primary and secondary currents while energized, and it has a function for determining the phase relationship between the primary and secondary currents, which allows for a reduction in inspection time.
Features:
- Primary current detection unit: Wirelessly transmits current values from the primary line (high voltage). The error range is minimized in three stages based on the current magnitude: 4A/40A/200A.
- Secondary current detection unit: As a device that transmits current to the main unit via wired connection, it is always set to a measurement range of 4A, and there are three units that can simultaneously connect R phase (yellow), S phase (brown), and T phase (black).
- Main unit: Utilizes the primary/secondary current detection units to collect data, synchronize time, and perform calculations. Based on the results, it alerts the user to the presence or absence of abnormalities in the MOF, allowing for the display, storage, and output of various data for user judgment. Inspection data is presented in detailed values such as measured values, ratio error values, C.T. ratios, etc., and can be stored for up to 10 units.
