SCR ELEKTRONIKS have developed primary and secondary Current injection test trolley for Switchgear manufacturers for testing of ACB , MCB , MCCB. It is low Voltage high Current source with control circuitry, digital read out for test current and trip time measurement. We can select different links of CT range as per the required test Current.
User defined continuous and short time duty cycle
Single / 3 phase operation possible
Test time indicator and controller
Portable (with lockable castor wheels) allows movement accross factory floors
Combined AC / DC operation possible as per customer specs
Can integrate temperature rise and measurement system
PC based operation possible as per customer specifications
Input supply: 415V two phase with MCB protection.
Digital Voltmeter: 3-½ digit (0 – 500 V AC).
Digital Ammeter : 3-½ digit ( 0 – 100% )
Variac for Current adjustment .
Test time indicator with four ranges .
Five CT ranges for selecting the test Current.
Indicator lamps : Power ON , Output ON , Overload.
The system can be customized for typical continuous duty and short time current values at a customized output voltage for 1 / 2 / 3 phases. Temperature rise test can be clubbed with the system with user defined channels of temperature measurement. The system can together be clubbed with secondary injection system also. Also, AC / DC injection kits are available
Primary current injection trolleys are used for high current testing of ACBs, SF6 CBs, VCBs and cable testing. They are also used to check the switchboards and current feeders, often in coherence with temperatrue rise measurement
