SURGE TESTER

Product Code : CTS006

Description: TYPE: SGNT10 This testing kit is capable of test insulation in transformers, particulars between turns, coil to coil which should be able to withstand surges due to transients, example, caused by switching of inductive loads or by lighting strokes. Transient high voltage pulses are applied instead of testing with continuous voltage (50 Hz.) or DC thereby, simulating actual fault conditions. The rapid rise time permits the detection of insufficient insulation that continuous voltage testing will not be able to detect. Solid state electronic control circuitry is provided to generate pulses at a rate of either 6 / mins. or 12 / mins. Successive pulses are limited to 50. After the 50th cycle the set automatically gets tripped off. Single over voltage pulse can also be applied with a specific push button operation. One voltmeter will indicate the amplitude of the output pulse. Pulse will appear between H. V. output terminal and ground. Output can be of either polarity i.e. positive or negative, selectable by polarity select switch. Input : 230 volts, 50 Hz, single phase, AC. Output : Pulsed High Voltage variable between 0 to 10 kV. The set consists of the following: * High Frequency High Voltage Pulse transformer. * Continuously variable auto transformer for pulse control. * Solid state switching components. * Capacitor & resistors to control pulse shape. * Current limiting resistor. * Pulse generating & control circuit consisting of solid state electronic components. * Indicators & Control switches. * Pulse height measurement circuit & indicator. * Mains switch, fuse, indicating LED & mains input chord of at least two meters length. * Coaxial H.V. cable of at least two meters length for connecting the output to the test sample.
