The relay is also having dedicated potential free contact for external ALARM This feature is very useful to give pre information to avoid any mal operation In such situation it uses the default setting and remains in protection mode 3 Working Principle and Design The ADR133A monitors HV and LV current of power transformer through respective CT The sample current values are processed by powerful DSP controller It converts these current samples into equivalent vectors and number of parameters such as RMS values of IHV and ILV and phases IHV represent HV current and ILV represent LV current Normally to match HV and LV CT ratio phase shift between two winding due to transformer vector group ICTs interposing CTs are needed In ADR133A ICTs are software selectable There are two separate ICT ratio and vector groups provided one for HV value and another for LV value After applying this corrective factor relay calculates operating and restraining signal from IHx and ILx IH1 and IL1 is HV and LV current after applying ICT correction factor x denote phase 1 for R 2 for Y and 3 for B Based on these settings the relay decides to operate or to restrain Operating Current Tox IHx ILx Restraining Current Ibx IIHxl 1 ILxl 2 Note Due to our policy to upgrade our products constantly we reserve the right to supply products which may vary slightly from that indicated above ASHIDA ELECTRONICS PVT LTD Plot No A 308 Ro
