The sets of load resistors RD are used to ensure proper operating conditions of measuring transformers (current and voltage). Beside classical 3-resistor sets for 3-phase circuits (3 x R), we offer RD-50 (2 x R) sets for transformers working in “V” arrangement, and resistors RD-50 (1 x R) for absorption of ferroresonance vibrations, designed for open delta system of voltage transformers.

Calculating of operating parameters of measuring systems, with a special focus on proper load of the measuring transformer, is facilitated by a manual provided by ZPrAE Sp. z o.o. named: “Measuring system – ensuring proper operating conditions of transformers”.
