EMC test generator for Slow Damped Oscillatory Waves

January 08, 2014 // By Graham Prophet
Teseq's NSG 3040-SOW is a stand-alone generator for slow damped oscillatory wave testing in single phase equipment up to 270 V and 16 A, in compliance with current testing standards IEC/EN 61000-4-18 and ANSI C37.90.1.

Suitable for power stations, substations, electric meter manufacturers, relays and switch manufacturers as well as EMC testing labs that already use Teseq equipment, the NSG 3040-SOW enables users to perform over-testing at test levels up to 4.4 kV. Features include selectable reduced source impedance as well as higher pulse rates which enable users to test under conditions that are closer to reality, ensuring their product will perform as intended in the real world.

Designed to complement Teseq’s line of NSG 3040 and NSG 3060 series of EMC test generators, the NSG 3040-SOW features the same 7-in. high contrast, colour touch-screen interface for set-up of test procedures. The generator can obtain quick, reliable results of standardised tests with a few clicks using the integrated Test Assistance (TA) function. The NSG 3040-SOW offers inputs supported by an integrated keyboard or thumbwheel with additional keys for sensitivity adjustment. It has Windows-based control software that simplifies test programming and compilation of complex test sequences composed of multiple waveform types. Specifications include;

Test voltage range from 0.2 kV to 4.4 kV

Oscillation frequency of 100 kHz and 1 MHz

Selectable source impedance of 200 Ohm and 150 Ohm

Pulse repetition rates exceed standards requirement

1 MHz pulse: From 1/sec to 600/sec, default is 400/sec

100 kHz pulse: From 1/sec to 120/sece, default is 40/sec

Ethernet port for external PC control

Approximate weight 25 kg

Dimensions 449w x 226h x 565 mm deep.
