The primary task of a voltage tester is to provide high-precision measurement results, which is the fundamental starting point of its design. From a circuit perspective, designers must select the appropriate sensor technology based on the target measurement range, such as low voltage (0-1000V), medium voltage (1kV-35kV), or high voltage (>35kv). Misali la, high-precision resistive dividers walima voltage transformateur (PTS) bɛ baara kɛ ka caya low-voltage scenarios kɔnɔ, ka sɔrɔ high-voltage scenarios bɛ tali kɛ dividers capacitives walima voltage sensors optiques (OVTs) kan walasa ka signal attenuation ni interference dɔgɔya.

For low-voltage (≤1000V) applications, an insulated casing (such as ABS + PC flame-retardant material, with a withstand voltage rating of ≥3kV) and a double insulation structure (basic insulation + supplementary insulation) are essential. For medium- and high-voltage (>1KV) Baarakɛcogo, sanfɛ-Volta isolation probes walima fibre-OPTIC transmission technology nafa ka bon.

Industrie automatique production lines kɔnɔ, miniaturisation (misali la, portabilité), jaabi teliya (sumani waati .<100ms), and IP65 protection (dust and water resistance) are key specifications. In addition, modular design concepts are becoming increasingly popular. Through pluggable functional modules (such as high-precision current probes and temperature sensor interfaces), users can expand the tester's functionality based on their actual needs, avoiding the increased costs of redundant functions or the impact of missing functions on efficiency.
