In the context of HT (High Voltage) systems, RMU (Ring Main Unit) typically appears as a compact, metal-enclosed switchgear unit designed for medium voltage applications. It contains essential components such as circuit breakers, switches, and protection devices, allowing for the safe distribution of electricity in a ring configuration. RMUs facilitate reliability by providing multiple supply routes, enabling quick isolation and maintenance without disrupting the entire network. They are often used in urban environments and industrial settings to manage power distribution efficiently.
Frist putt of the main incomer HT side then Rack out the breaker and put the LOTO after that Discharge the cable Both side (HT/LT).
You need to specify the phase. I assume it is 3 phase system. Then the HT current is 30.3 amps
Dielectric Strength of Vacuum is more than that of Air. In HT voltage is more than LT. So VCB is used in HT & ACB in LT. Rakesh Gaikwad

Because the current is smal , the votage > current x ressistance willbe small and therefore will be only a smal percentage of the ht.
taking the tablet any problem my body
Note the HT side VOLTAGE,Current,P.F at the same time calculate the L.T side Voltage,current ,P.F.Convert the L.T side V,I,P.F to H.T side by using transformation ratio and calculate the Power in KW for both H.T side and L.T with respect to H.T Then Loss=H.T side power in K.W-L.T side power in K.W with respect to H.T
on the cab side of the motor. Just follow the ht leads!!
High current coming now that's why use the vcb
