three. CZPTtrical Design and style Common

 

three.one Transformer.

 

The substation is created to cater for bushings on reverse sides of the transformer. 

The bushings on the transformers must be coated, if possible by utilizing cable entry transformers. If not, then appropriate earthed metallic cable addresses shall be installed on the transformer to eliminate all bare reside connections.

 

3.2 High voltage switchgear

 

Numerous types of substantial voltage switchgear are accessible which will go over all programs. Typical 1 is a Ring Primary Unit comprising two feeder cable switches and one particular fused switch/circuit breaker for 1 transformer

 

3.3. Low Voltage Switchboard

 

The low voltage switchboard will have a load break change for each transformer. The customer’s supply is to be protected with either fuses – up to 1200 Amp (two stripe fuses in parallel) – or circuit breakers – previously mentioned 1200 amps. The reduced voltage board also provides the facility for giving the substation’s light-weight and energy and ventilation and sump pump tools if set up and also is made up of greatest need indicators.
