Test Equipment Description

EM Test OCS 500N6F Application:

OCS 500N6F - Compact testers for fast/slow Damped Oscillatory Waves and Ringwave

The OCS 500N6F series includes the test capabilities for fast damped oscillatory waves at 3 MHz, 10 MHz and 30 MHz up to 4.4kV and is extendable for slow damped oscillatory waves at 100 kHz / 1 MHz up to 3.0 kV (as per EN/IEC 61000-4-18) and for ringwave up to 6 kV as per EN/IEC 61000-4-12.
Damped Oscillatory Waves are repetitive transients mainly occurring in power, control and signal cables installed in high voltage and medium voltage stations, divided into slow and fast damped oscillatory waves. The Ringwave is a non-repetitive damped oscillatory transient occurring in low-voltage power, control and signal lines supplied by public and non-public networks.

Standards Met:

  • ANSI/IEEE C37.90
  • ANSI/IEEE C62.41
  • EN 61000-4-10
  • EN 61000-4-12
  • EN 61000-4-18
  • IEC 60255-22-1
  • IEC 61000-4-10
  • IEC 61000-4-12
  • IEC 61000-4-18
  • IEC 61000-6-5
  • IEC 61850-3
  • IEC 62052-11

EM Test OCS 500N6F Details:

The basic equipment includes the fast damped oscillatory generator with 3 MHz, 10 MHz and 30 MHz for up to 4.4 kV acc. IEC 61000-4-18.

The OCS 500N6F comes with a built-in coupling/ decoupling network for either single phase or three-phase and is rated for currents of 16 A or 32 A per line.

Optional Modules:
Slow Damped Oscillatory Waves with 100 kHz / 1 MHz reach up to 3kV. The module comply with EN/IEC 61000-4-18 and also with the requirements to test protective relays as per ANSI/IEEE C39.70.
Ringwave Module with capability of up to 6 kV complies with the Ringwave requirements of IEC 61000-4-12 ANSI/IEEE C62.41

Accessories:

MS100N The MS100N is a 1sqm magnetic field coil as specified in IEC/EN 61000-4-10. Its design allows easy moving of the coil. The field coil is adjustable in height and allows for 360degree rotation.
The MS 100N is directly connected to the corresponding HV output of the OCS 500N6 to generate damped oscillatory magnetic fields as per IEC/EN 61000-4-10, up to level 5.
