[1]   Click to Enlarge SURGE TESTER 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.

Supplies : Internal auxiliary supply will be there to generate 24 volts DC or 50 volts DC for the main test, to drive electronic gears, to drive relay etc. Stopping Mechanism : The drive will be stopped after certain duration by a timer .By this time only 50 meters of wires tested through the * Mercury Pool. See Enlarge Click to Enlarge Power Thyristor Test Jig The Test Jig is capable to conduct three major tests like, OFF state forward and reverse blocking voltage, DC triggering characteristics, ON state current conduction & voltage drop measurement on SCR under test. Input voltage: 230 volts, 50 Hz, single phase, AC. Output-1 [For Blocking state mode] Continuously variable 0 to + 3 kV DC peak. Max. Capacity: 200 mA. Metering: Digital voltmeter & ammeter to read peak output DC voltage & current. Protection: One snap acting over current protective device which will "trip off" the output voltage circuit in case of breakdown of the thyristor under test. Output-2 [FOR DC triggering characteristics mode] Continuously variable 0-15V DC output with current control facility from 100mA to 1A. This power source is isolated from the power side. Metering: Digital voltmeter & ammeter to read output DC voltage & current. One DC triggering module named as gate power source. Output-3 [FOR ON state current conduction & voltage drop measurement mode] Continuously variable DC source to check forward voltage drops of the device & loading of the device up to 100A peak DC. Metering: Digital voltmeter to measure forward drop peak voltage of the thyristor under test & digital ammeter to read output direct peak current. Protection: Snap acting over load circuit. One Test Chamber is provided with the test jig. The sample under test is fitted within this Test Chamber during testing. Interconnecting cables are also provided.
