Conducted Susceptibility Laboratory

SAMEER centre for electromagnetic has the test facility to test the conducted immunity tests for electrical and electronic equipments as per IEC, BS EN and ISO standards. The following tests are having the test facility for doing the conducted immunity tests: 

1. Electrostatic discharge (ESD) immunity test


















for simulating the static electric discharges, from operators directly, and to adjacent objects. ESD test facility is equipped with static electric charge generator with different types of energy storage capacitor and discharge resistance as per IEC, BS EN, ISO & SAE standard requirements.

2. Electrical fast transient (EFT) immunity test
for simulating the electrical fast transients originating from switching transients (interruption of inductive
loads, relay contact bounce, etc.). EFT test facility is equipped with EFT generator, coupling and decoupling networks for coupling the transients on DC,single phase and three phase supply lines and capacitive coupling clamp for coupling the transients on signal and control lines as per IEC and BSEN standard requirements. 

3.High Energy Surge immunity test
for simulating the surges caused by over voltages from switching and lightning transients. Surge test facility is equipped with 1.2/50µs and 10/700µs combination wave generator with different type of coupling and decoupling networks for DC, single phase, three phase supply lines and unshielded unsymmetrical & symmetrical interconnection lines as per IEC and BS EN standard requirements.

4. Damped Oscillatory waves immunity test
for simulating the non-repetitive damped oscillatory transients (ring wave) occurring in low-voltage power, control and signal lines supplied by public and non public networks and repetitive damped oscillatory waves occurring mainly in power, control and signal cables installed in high voltage and medium voltage stations. This test facility is equipped with test generator, coupling and decoupling networks for DC, single phase, three phase supply lines and signal lines as per IEC and BS EN standard requirements.

5. Pulse magnetic field immunity test
for simulating the pulse magnetic fields generated by lightning strokes on buildings and other metal structures including aerialmasts, earth conductors and earthnetworks. This test facility is equipped with test generator, induction coil as per IEC and BS EN standard requirements.

6. Voltage dips, short interruptions and voltage variations immunity test
for simulating the dips and short interruptions caused by faults in the network, primary short circuits and sudden large changes of load and for simulating the voltage variations caused by continuously varying loads connected to the network. Voltage dips, short interruptions and voltage variations test facility is equipped with test simulator, coupling and decoupling networks for DC, single phase and three phase supply lines as per IEC and BS EN standard requirements.
