FAQs 6

What are SseG inverters used for?

Inverters can also be utilized to convert power produced by wind, hydro, battery energy storage, etc. to grid compatible electrical power. According to the South African Distribution Network Code, utilities are obliged to provide an offer to connect SSEGs under the conditions in the connection application.

What are the installation requirements for SseG inverters?

5.4.9 Installation requirement: Inverters equipped with the NEB control port only, shall have external electromechanical NEBs installed that are SANS/IEC 60947-1 and SANS/IEC 60947-4-1 certified. Inverter based SSEGs shall open their SDUs within 500 ms if the threshold for DC current injection is exceeded.

Does Sans 10142-1 cover off-grid electricity generation?

Stand Alone of Off Grid electrical generation systems like solar PV or wind turbines as this is covered in clause 7.12 of the SANS 10142-1. The SANS 10142-1-2 compliments the base document. Questions?

What is a small-scale embedded generator (SseG)?

An embedded generator with nominal capacity of less than 1 000 kVA, connected to a single-phase, dual phase, or three-phase low-voltage supply is defined as a small-scale embedded generator (SSEG). Parallel operation means that both the SSEG and the utility are able to supply power to the same AC system at the same time.

Do TS substations comply with grid code protection requirements?

All plant connected directly to a TS substation shall comply with the Grid Code protection requirements described in section 5. This shall include busbars supplied directly from TNSP transformers, and lines, transformers and shunt capacitor banks directly connected to that busbar.

What are the installation requirements for SseG meter?

6.2.2 Installation requirement: The SSEG shall have a means of preventing power to flow into the utility supply installed. 6.2.3 Installation requirement: The meter shall record any power that flow into the utility supply as energy consumed.
