Измеритель напряженности электрического поля (230 В, 50/60 Гц)
Experiment topics:
• Introductory experiments on the functioning of the apparatus
• Electrostatic tests
• Measurement of static electric field strength
• Capacitor tests
• Measurements of potential with an electrostatic meter
Instrument for static measurements of electric field strength or electrical potential.
A star-shaped modulation vane-wheel connected to earth is mounted a short distance in front of a measurement electrode, also star-shaped. Influenced by the electric field, the charges generate an alternating current proportional to the field strength. This alternating current is measured via a selective amplifier without the electric field experiencing any average energy loss over time.
When used in conjunction with voltage measurement plates, the instrument can be used as an electrostatic voltmeter. The device is protected against excess voltage. A standard DC voltmeter can be used for display.
Max. output voltage: 10 V
Measurement ranges: 1 V output can correspond to:
100 V/cm, 300 V/cm, 1000 V/cm
10 V, 30V, 100 V (with 1x voltage measurement plate)
100 V, 300 V, 1000 V (with 10x voltage measurement plate)
