Damped oscillatory waves are phenomena associated with the opening and closing of High Voltage (HV) busbars in power transmission stations. The physical environment influences the fundamental oscillation frequency and repetition of the impulses. Repetition frequencies are dependant on the power frequency and distance between contacts. For gas insulated stations this could be up to 5kHz.
The new IEC61000-4-18 standard introduces additional fast damped oscillatory waves at frequencies of 3MHz, 10MHz and 30MHz. These are for testing of signalling and control equipment installed in Gas Insulated Substations (GIS) where the transients occur in metallic enclosures containing SF6 gas.
MIG-OS-OM-EXT has been designed to add fast oscillatory wave capability to existing EMC Partner generators.
MIG-OS-OS1 and MIG0603OSI generators deliver 100kHz and 1MHz slow damped oscillatory waves that were previously included in the IEC61000-4-12 standard.
As the application is for power distribution stations, the equipment to be tested is generally connected to 3-Phase power lines. CDN3000-06-25 (manual) and CDN3000A-06-25 (automatic) enable coupling of both fast and slow oscillatory waves. |

Simply the best HARMONIC and FLICKER test system available today. HAR1000 does not require expensive and bulky AC sources, it uses a novel technique to provide active compensation of distortion on the national power mains.
Featuring dual analysers, the input and output signal are constantly monitored to ensure compliance. HAR1000 conforms to the latest IEC61000-3-2 Edition 2 but also allows testing to previous standard editions.
HAR1000 can be enhanced with the following accessories.
HAR-EXT1000, three phase system
Adds two further phases to the HAR1000. Simple connection without any hardware modifications mean this powerful extension can be added at any time to an existing single phase system.
HARCS Immunity software
This package can be added to both the single and three phase systems. It extends the system’s emission capability to include power line immunity tests such as harmonic immunity according to IEC61000-4-13, voltage fluctuations according to IEC61000-4-14 and ripple on DC according to IEC61000-4-17.
Adding the EMC Partner PS3, allows testing to IEC61000-4-28 for frequency fluctuations.

| California Instruments cabinet systems are carefully designed and manufactured to provide maximum system performance and reduce installation cost. The various elements that make up an integrated high power AC test system are carefully assembled in a high quality 19 inch cabinet. All input and output wiring is properly sized and routed for optimal performance and safety. Configuration problems or wiring mistakes are eliminated when ordering a cabinet based multi-box power system like the 15003iX or a three phase compliance test system like the 30003iX-CTS. This translates into faster setup time and reduced installation hassles upon receipt of your power system. |

| Testing of Electricity Metering equipment, takes many different forms. Apart from accuracy and stability, meters must also be tested against interference conducted on the elctricity cables. This can be in the form of impulses generated by lightning events, switching action in the mains network or insulation breakdown. EMC Partner specializes in designing test equipment to meet the international standards for impulse testing of energy meters. IEC61036 and IEC62052 are typical standards for class 1 and 2 metering equipment. |

| Self-adjusting fault indicator for system-wide application. Provides clear visual indication of fault path to line crews in the field to help reduce fault-locating time. Automatically adjusts its trip value based on the load current, eliminating the need to specify a trip value. Allows line crews to easily distinguish between temporary and permanent faults. The inrush restraint feature allows coordinated integration with automatic reclosing schemes. Patented Ramp Down Restraint feature prevents false activation after extended circuit outage. Distinct eight-hour temporary fault indication allows line crews to investigate the cause of self-clearing faults and successful trip and reclose operations to improve circuit reliability. |

| The ground resistance of substations can be measured with two auxiliary electrodes which are put into the ground. To avoid influences from the mains current and its harmonics, this measurement should preferably be carried out with 128 Hz.The high output power of the CPC 100 ensures a high ratio of the signal level to the noise level. Thanks to the signal processor technology, the measuring procedure is very selective and disturbances by ground currents are reduced to a minimum. |
