Description
Clamps measure current without breaking the circuit, which suits an operating substation. Reading variation is no more than 0.75 %. Lower ranges tolerate overload up to 5 times. The insulation withstands 2 kV, 50 Hz for 1 min. ВАФ-85-М1 has dimensions 260 × 160 × 185 mm, weighs up to 3.5 kg and comes with a clamp adapter, five leads and a contact clip. Phase angles serve vector diagrams of currents and voltages in protection and automation checks. Spellings vary: ВАФ-85-М1, ВАФ-85М1, ВАФ 85-М1, VAF-85-M1. These are the same instrument.
How to choose
The choice depends on the model and circuit. ВАФ-85-М1 usually needs the full kit with a clamp adapter. For a replacement of ВАФ-4303 or 4333, name the exact designation. Ask the USK ENERGY manager about kit, calibration and version when ordering.
