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.
SCR ELEKTRONIKS make Programmable High Voltage Tester model: PHVT is the unique High Voltage breakdown tester indispensable for all types of Industrial grade Electrical products manufacturers for carrying out H.V.Test according to different standards. High Voltage Test is important to ensure the satisfactory and safe performance of all types of electrical products. It is carried out by applying a specified voltage to the object under test gradually and then maintaining the same voltage for the desired time period. Then the applied voltage is gradually reduced at uniformed rate. In case of breakdown the voltage must be switched off instantly to avoid the burn out. It is also necessary to know the leakage current for a specified voltage. `SCR’ make programmable High Voltage Tester, Model: PHVT-10KV, 100mA /AC DC incorporates all the desired features to carry out the H.V.Test according to the procedure laid down in the standards.
SCR ELEKTRONIKS have developed SECONDARY CURRENT INJECTION TEST TROLLEY for Switchgear items, CT manufacturer and where three phase current application is called for. It is low Voltage, 3 phase Current source with control circuitry, digital read out for test current and trip time measurement. We can select different CT ranges for each phase independently and adjust the current as per the required test Current.
SCR ELEKTRONIKS has developed SENSITIVITY TEST BENCH FOR RCCB. This panel is used to perform Verification of the operating characteristic test as per IEC 61008-1clause no.9.9.2.1, 9.9.2.2, 9.9.2.3, 9.9.2.4, Verification of trip free mechanism test as per IEC 61008-1 clause no.9.15 and Verification of the operation of test device at the limits of rated voltage test as per IEC 61008-1 clause no.9.16. The test bench is designed with state –of-art Technology and to test entire range of RCCB/RCBO as per IEC 61008-1, IEC 61009-1.
The circuit breaker is secured to the vertical board in such a way that the distance of horizontal axis of the sample is 180 mm from the platform the vertical board being in, so fixed that the distance of the mounting surface is 200 mm from the hinge.
On the surface, opposite the mounting surface of the circuit breaker, a supplement mass is fixed so that the static force on the metal stop – plate is 25 N in order to ensure that the moment of inertia of the complete system is substantially constant.
The test setup is require for Short Time Over current Test, Fault Current Making Capacity Test and Short Circuit current Carrying Capacity test on Prepaid Energy Meter as per IS 15884
