A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.

The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.

A 132 kV substation is normally called a grid substation. It would normally use two or more 132/33 kV transformers rated at 90 MVA, or two or more 132/11 kV transformers rated at 30 MVA.
In the UK, 11-kV power lines are part of the distributionsystem, not the transmission system. The system is split as follows:transmission-system voltages: 400 kV, 275 kV, and 132 kV.primary-distribution system voltages: 66 kV and 33 kV.secondary-distribution system voltages: 11 kV and 400/230 V
It isn't. In the UK, transmission and distribution voltages are 400 kV, 275 kV, 132 kV, 66 kV, 33kV, and 11 kV.
To test an a.c. underground cable's insulation, that insulation needs to be tested at a voltage higher than its rated voltage, continuously (a.c. varies, so is unsuitable), for a specified period of time, and with the resulting current being monitored throughout the test. The test voltage/duration applied will be laid down according to the standards of the authority responsible for the electricity distribution system (derived from the cable manufacturers). Typically, an 11-kV underground cable is tested a 17 kV (d.c.) between lines, and at 10 kV (d.c.) line to earth. The duration of the test is typically 5 min. Initially, the current will include the cable's charging current (the cable behaves as a capacitor), but then settles down to the leakage current -typically about 0.2 mA (if attached equipment is not taken into account).
The lower-case 'k' in 'kV' (not 'kv') is a multiplier, representing 'kilo', meaning 'a thousand times', and the upper-case 'V' represents 'volts', the SI unit for potential difference. So a '220-kV' cable has a line voltage (voltage between conductors) of 220 kV.
It is not necessary to design an 11 kv underground cable. There are several 11 kv underground cables already on the market. You can choose exactly which cable will fit best for your project and purchase it.
It used to be a convention to add 10% to allow for transmission losses, so the voltages were always described as 11 kV, 33 kV, 66 kV and 132 kV. Later standards in the UK grid are 275 kV, which is a multiple of 11, and 400 kV which is not.

5 kV ac means 5 kV rms, which represents a peak voltage of 5 x sqrt (2) kV, or 7.07 kV. So the dc test should provide 7070 volts.
