Datasheet

An easy-to-use, stand-alone generator for slow damped oscillatory wave testing in single phase equipment up to 270V and 16A has been unveiled by Teseq. The NSG 3040-SOW is in compliance with current testing standards IEC/EN 61000-4-18 and ANSI C37.90.1. It is designed for use by power stations, substations, electric meter manufacturers, relays and switch manufacturers as well as EMC testing labs that already use Teseq equipment. It enables users to perform over-testing at test levels up to 4.4kV.

The generator features unique capabilities including 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 new generator features the same 7in. high contrast, colour touch-screen interface to enable quick and user-friendly 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. It offers inputs supported by an integrated keyboard or thumbwheel with additional keys for sensitivity adjustment. The new generator features Windows-based control software that simplifies test programming and compilation of complex test sequences composed of multiple waveform types.

The test voltage range is from 0.2 kV to 4.4 kV with an oscillation frequency of 100kHz and 1MHz. Other features include selectable source impedance of 200Ohm and 150Ohm. An Ethernet port for external PC control. Dimensions are 449 mm (17.7in.) wide x 226 mm (8.9in.) high x 565 mm (22.2in.) deep.
