6.2 Load Break Oil-Immersed Rotary Switches (LBOR)
WARNING:
Do not operate load break equipment if a fault condition is suspected. Doing so can cause
an explosion orfire.
WARNING:
Use a hotstick to operate transformer load break equipment.
WARNING:
After operating transformer load break equipment, check that voltages at transformer
terminals are the expected values. Checking voltages verifies that load break equipment operated
properly and that electrical circuit conditions are as expected.
WARNING:
Before servicing transformer secondary connected equipment, verify that all transformer
secondaryterminalshavezerovoltageandgroundthetransformersecondaryterminalsfollowing
industryaccepted safe grounding practices. Grounding secondaryterminals protects against situations
such as a standby generator energizing transformer from the secondary circuit.
Two-Position LBOR Switch
The Two-Position LBOR Switches (Fig. 15) are provided optionally in padmount transformers to achieve load
breaking or making and loop feed switching. LBOR’s will have a hotstick operable handle
Multiple 2-Postion LBOR Switches may be utilized to achieve loop-
Feed switching (Fig.15A)
The spring-loaded activating mechanism of the switch ensures quick load break or load make operations in
less than one cycle, and should be performed with a hotstick
