Specification for 11kV Vacuum Automatic Recloser by Kenya Power and Lighting Company Limited (KPLC)

The Rockwill standard smart recloser offers high precision with a wide measuring range (2A–16,000A). Simply ensure your normal current is within this standard range when making a selection.

Yes. In addition to the standard 2A–16,000A range, Rockwill provides custom-configured units for ultra-low current measurement and protection in the 0.1A–2A range.

Specification for 11kV Vacuum Automatic Recloser by Kenya Power and Lighting Company Limited (KPLC) defines minimum design, material, rating, testing and acceptance requirements for three-phase pole-mounted vacuum reclosers deployed on KPLC 11kV overhead distribution network. It specifies equipment rated voltage 12kV, minimum 630A continuous current, IP65 control cabinet, and maximum four programmable auto-reclose operations before lockout.

Specification for 11kV Vacuum Automatic Recloser by KPLC stipulates 1 minute power frequency withstand voltage of 42kV rms and lightning impulse withstand voltage of 75kV peak (1.2/50μs). The solid dielectric insulation system shall maintain stable performance under tropical Kenya field conditions including UV radiation, dust and high humidity.

Specification for 11kV Vacuum Automatic Recloser by KPLC requires the recloser to provide up to four programmable auto-reclose operations and lock out upon permanent faults. This protection sequence differentiates transient overhead faults from permanent faults, restoring power rapidly and reducing outage duration for rural 11kV feeders.

Specification for 11kV Vacuum Automatic Recloser by KPLC mandates the control cabinet enclosure to achieve IP65 protection class complying with IEC 60529. The cabinet door shall be fitted with padlock point compatible with KPLC standard safety padlock to restrict unauthorised access to protection and control circuits.

Specification for 11kV Vacuum Automatic Recloser by KPLC requires complete IEC type tests including IEC 62271-121 recloser dedicated test items, and KPLC witness test can be arranged. The vacuum recloser automatically detects, isolates overhead faults and recovers supply for transient faults, cutting manual fault patrol workload and improving overall reliability of KPLC extensive 11kV rural overhead network.
