<p>A detector, especially a high voltage detector has a casing (1) made of a non-conductive material with a feeler (6), test contact (5) and at least one pair of light-emitting diodes (4) projecting therefrom; said diodes being controlled by a second astable multi-vibrator (60) mounted inside the casing (1); said multi-vibrator being connected to a control input of a first astable multi-vibrator (50) with an electroacoustic transducer (9) with the proviso that the first and second astable multi-vibrator (50, 60) are connected to a switching block (40) having an accumulator (7), the test contact (5) and a processing block (30) connected thereto; an input of the processing block (30) being connected with a transducer block (20) having the accumulator (7), test contact (5) and processing block (30) connected thereto; an input of the processing block (30) being connected with the transducer block (20) having the feeler (6) and anti-electrode connected thereto.</p> |
