5 seconds.Insert 179 (Extract from the CEE Publication 17, dated 1958) The insulating material components containing voltage-carrying parts must resistant creepage current. The entire width both rounded edges must contact the test object. the results are doubtful, the test must repeated with new set test objects. The solution’s volume resistivity 400 ohms 25° This equivalent a concentration approx 0. There may breakdowns sparkovers between the electrodes before a total drops have been applied. A revision this testing method pending.9 The circuit includes overcurrent relay that has a minimum triggering delay 0.0 ±0. 4. This test not performed with equipment rated nominal voltages V or less. When the electrodes are short-circuited, the total impedance of the circuit adjusted variable resistor for current 1. the surface.215, are placed the surface the test object, shown this figure.1 A, for cos 0. The surface the test object moistened between the two electrodes with drops solution ammonium chloride and distilled water. Two electrodes, made sintered Wolfram carbide another sufficiently corrosion-proof material and whose dimensions comply with Fig.1%. The solution is dropped from height mm. Non-ceramic materials are tested specified below. Each electrode exerts force approx. A flat surface the test object with area least (if possible) placed horizontal position. The interval between the drops seconds. The electrodes are connected 175-VA(/50-Hz source (practically sinusoidal). The drop volume ±5-mm3. The electrodes must clean, properly rounded and properly positioned at the start every test.
