Voltage & Current Injection Trolleys, High Current Sources and Electrical Load banks for Testing & Quality Assuarance application

We design and manufacture Voltage & Current Injection Trolleys, High Current Sources and Electrical Load banks for Testing & Quality Assuarance application.
Givent below is an illustrative list of such products. If you are looking for a particular set-up that is not listed below, please write to us. We welcome custom design enquiries from manufacturers of electrical appliances & test laboratories.


Current Injection Trolleys (Primary and Secondary)

Current Injection Trolleys are used for high current testing of Air Circuit Breakers, Vacuum Circuit Breakers, SF6 Circuit Breakers and other high current devices to verify their current breaking characteristics. The trolleys are of two types: Primary Injection Trolleys and Secondary Injection Trolleys. Primary Injection Trolleys have a specially designed high current source to inject actual breaking current of the order of 1000 Amps in to the Circuit Breaker (line current as experienced by the CB) to checked if the Circuit Breaker opens (trips). While secondary injection trolleys check the working of the relay circuit of the Circuit Breaker by injecting a downscaled value of current (much less than 1000 A) into the secondary of the current transformer of the relay circuit in the circuit breaker.


AC/DC Voltage Source

These are customized voltage sources of variable output voltage, generally with a voltage range from 0 to 1000 V for various applications (The range can be extended if required). They contain a meticulously designed power (voltage) source capable of supplying the rated voltage and current.


Inductive & Capacitive Electrical Load for testing of Switches & Sockets

Electrical loads are nothing but resistive, inductive and/or capacitive load banks meant to simulate real world conditions with respect to voltage, current and power factor that the switches or sockets under test are subjected to. Over the years SCR ELEKTRONIKS have developed empirical knowledge of designing iron core and air core inductors expertise to supply customer requirements of loads with a considerable degree of accuracy.
