132kv MOCB acceptable value of somthing 150 micro ohms.
Primary substation - when the transformer is HV/MV or MV/MV. e.g. substation designed for 132kV/33kV or 230kV/22kV or 33kV/11kV etc stepped down for MV distribution (mainly for utilities and heacy industries) Secondary substation - when the transformer is HV/LV or MV/LV. e.g. substation designed for 11kV/400V or 6.6kV/400V etc stepped down for LV distribution (mainly for residential, commercial) sometime referred to as a kiosk substation.
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
it depends on the specification,,,,,,in saudi arabia as per sec standards 152kv voltage should be applied for a period of one hour.
Its just a matter of standard. In my area, for instance, we use 13.2 KV for distribution lines, and 69 KV / 138 KV for transmission lines.
Sir I am Imran khan in nepal my problem is 6000KVA Step down Transformer is not charging. Transformer Pri- 33000V /105A Sec- 6900V / 502Atransformer all test (open & short circuit ) good . but problem is HT(IR)= value this time IR value 50M ohmBefore 3days HT(IR) = value is 7000M ohm suddenly start Transformer result is Transformer not charging & HT(IR) value is down 50M ohm.
132kv MOCB acceptable value of somthing 150 micro ohms.
9 insulators
it means..it is stepping up the power of 132KV to 380KV on the transmission lines.
The safety distance from a 132 kv powerline is 1.4 metres

Refer IEEE 80- 2003 For Design of grounding of 132kV substation.
Usually HV is 33KV and 66KV, EHV is 132KV, 220KV and 400KV and UHV is 800KV and 1200KV

the general height is 25-27mts,the first conductor is placed 17mts above the ground and rest of conductors placing 1st-2nd is 3.1mts and 2nd-3rd is 2.6mts
transmission and distribution of electricity are the way of regulate voltage to the minimum rate in which can be benefit to the consumers. From generating station , voltage generated is up 16/25kv which step up upto 330kv this generating voltage now step down in the transmission station through the step down transformer which is 132kv this voltage now transmitting to distribution station where voltage now step down to 33kv, this 33kv now stepdown to 415v for three line and 240/220v for a line for the uses of consumers.
