The IED monitors online bushing’s insulation condition and sends alarms for incipient to advanced defects, avoiding catastrophic failures. The BM uses measurements and algorithms to supervise dielectric’s tangent delta (or power factor), capacitance and leakage current, as well as the evolution trend of these parameters.
Performs the online monitoring of membrane or bag rupture, based on the principle of light reflection, sending alarm if detected undue presence of oil.
It performs the conversion of temperature measurements, current loop and tap position on analog output proportional current. It has galvanic isolation between input circuits, output and power.
Indicates remotely until 8 measurements of sensors installed on transformers. The input variables are individually configured by the user with the beginning and end of measuring range.
