Switching and Earthing Operating Procedure

Switching and Earthing Operating Procedure

Switching and Earthing Operative Procedure in Electrical Energy Network


The keywords of this article are Switching & Earthing; we are not going to learn technical details about switching and earthing procedures in this piece, but we would like to keep in limit our focus on the key points to the safe operation of switching & earthing system.

The Switching

How keep your switching system safe and healthy in the electrical energy transmission and distribution network? Let’s review some important points that will keep you a smarter switching operator.

Circuit Breakers and Isolator Operation

1.     Don’t allow switching or any operation in a system without clear permission of the controlling authority except in an emergency case for personnel or property;

2.     System control authority should directly communicate with an authorized person who will operate the switching;

3.     If direct contact is not possible for controlling authorities, the message may be relayed by a third party with written down without any alteration or abbreviation;

4.     If a switching or operating message send by any wireless devices then the receiver will write the message and readout to the sender to ensure that it has been received accurately;

5.     The circuit Breakers or Isolators operator should carry on the message from control authorities without delay  regarding switching or operation;

6.     If emergency switching is required to save the life or property, the report must be relayed to control authority as soon as possible;

7.     If any fault is visible to any equipment, operator must  inform to controlling authority immediately before operation or switching;

8.     Very details switching and operation record must maintain in a station Log.

The Earthing

The earthing switch is very much related to switching or operating the circuit breakers and isolators. To ensure life and property isolator and earthing switch must be operated safely.

Circuit Main Earth or CME Operation

The Circuit Main Earth or CME must be operated under the supervision of authorized seniors and after clear instruction from the controlling authorities. The position of the earthing and location of each connection must be recorded in the station Log.
