Connecting to the grid?
Due to the widespread increase in the use of renewable power generation systems, the risk of causing inadvertent damage to the grid is increasing.
Ensuring a safe and reliable connection to the grid has never been more important to network operators and energy companies, with regulatory legislation recommending that connection systems should incorporate the use of a mains decoupling relay.
Bender UK’s VMD460 is compliant with G59-3 and works by disconnecting power generation systems from the grid, when voltage/frequency thresholds are infringed.
Product Benefits
Product users benefit from:
- Reduced commissioning & installation
- No connection to a PC or other device is required to set up, commission, or change operating threshold parameters
- Simpler than ever to protect the critical link between renewable power generating equipment and the National Grid
