Sakova A.C. High Voltage Breakdown Testers basically consist of a Double Wound High Voltage Transformer with the H.T. end brought out and terminated on a spring loaded prod for ratings up to 5 KV, or the H.T. end is brought out on a bushing for higher ratings. The lower end of the H.T. winding is at near earth potential and is also brought out, through intermediate circuitry and is terminated on the EARTH connection. The intermediate circuitry included at the lower end of thee H.T. winding enables tripping of supply to the H.T. Transformer, if the current through the test piece exceeds a pre-set value. The low voltage winding of the main HV Transformers is rated for 230 Volts or as specified and is energized by means of a VARIAC through a fuse link and an intermediate contactor/relay. The provision of VARIAC enables gradual application of high voltage to the specimen under test. The “Zero start” interlock switch is provided. Indicating Lamps are provided on the panel of the instruments to indicate “MAINS ON” and “H.T. ON”. A Voltmeter is provided on the panel to indicate the output high voltage. The voltmeter is connected on the low voltage side of the main transformer but is calibrated to read the H.T. Voltage directly. The calibration is carried out at no load. If the failure of the test piece occurs, the supply to the Voltmeter is maintained, although the supply to the HV Transformer is instantaneously cut-off. The voltmeter, therefore, indicates the voltage at which the test piece has failed. The testers of ratings up to 10 KV are housed in a sheet metal housing while those of ratings above 10 KV comprise of two units, viz., a Control unit and an HV transformer unit, made of sheet metal. The Testers are available for output voltages up to 100 KV and different current ratings, as desired.

The set provides three current generators and four voltage generators. With these sources, complete test system for  testing of virtually all types of single or  three phase  protection equipment viz. Electromechanical, Static and Numerical relays. Various primary switchgear testing can also be performed. Since all the voltage and current sources have floating ungrounded neutral which allows all the sources to be used either separately, in parallel or in series. This feature becomes useful when higher currents, voltages or VA ratings are required.  Other fields of operation are Plotting of CT excitation curves, Ratio Tests of CT\'s and PT\'s and Primary Injection in single or three phase switchgear. 6 sets of variable current sources for testing O/C, E/F, S/C and Differential Relays are available. A variable 3-phase Voltage source is available for testing Directional and Power Relays. In conjunction with a Phase Shifter, all types of relays except the Frequency relays can be tested.Specifications:Input: 415 V, 3-phase, 50 Hz, + 10%  or 240 V, 1-phase (for 1 phase operations).Outputs: A.
