Monitoring and bug fixing of electrical equipment
first. Monitoring and debugging systems and electrical equipment in building
two. Monitoring and correcting faults of transformer
monitoring and debugging systems and electrical equipment in building maintenance (maintenance) must be continued and each time repair. Should you create a full service history for the sake of analysis and prevention in
the future. Monitoring can be divided two ways:
1. Check with your senses. Check the condition of electrical equipment by voice or touch, smell, see
2. Check with a test tool Most use a multimeter Makers Insulation tester meter or meter resistance grounded. Monitoring tool, one that can create applications with a simple method over time. Pour Slam sites
using only Slam Camp is a testing
circuit breakers force of less
than. Circuit breakers first phase consists of CB 1 terminal with container load center (Load center) is applied to the system. 1st phase
b. Circuit breakers third phase will have three terminals (3 Pole) CB series are used with three-phase
(a) 1 Pole
(b) 2 Pole1.
The check circuit breakers.
