It is an most economical effective device for step less and continuous voltage control of Single Phase and 3 phase AC voltages for numerous applications for the industrial and Laboratories usages for testing and calibration purposes.
Impulse Voltage test systems are mainly used to check insulation performance of HV apparatus including Transformers, Reactors, Power Cables, CT/PT/CVT, Insulators, Bushings, Lightning Arrestors, GIS Switchgears, Motors / Generators etc. IVG are mainly used to generate standard lightning impulse full waves, Switching Impulse wave, impulse voltage ranges from 5kV to 500kV, energy from 2kJ to 50kJ. It can be used to carry out steeping and oscillating impulse test by adding some extra component. It operates with a PLC based control system. Charging time and charging voltage can be selected. Once the selected charging voltage has been reached, a trigger pulse initiates the firing of the lowest spark-gap of the impulse generator. When all the spark-gaps fired all the stages are connected in series thus multiplying the impulse voltage. The impulse voltage divider reduces the impulse voltage to a value that the measuring and recording instruments require.
Kilo Volt Meter (kV) meters used to measure the kilo volt value of an Instrument Transformer, CT/PT etc. The unit is used for higher value calibration with a wide range from 1% to 110%. Kilo Voltmeters are highly accurate, portable voltage measurement systems traceable to NABL standards. The Kilo meter series consists of a high voltage divider assembly, a precision readout device and interconnection leads. The battery operation makes the system completely portable for field testing while the precision divider assembly and readout device makes it suitable for laboratory use.
