Testing Insulation Resistance Using Megger Test Equipment

POSTED BY Protec Tech Team

Insulation plays a very important role in an electrical system. Without electrical insulation, the electricity flowing in the conductors is exposed to short circuit to other conductors or create the risk of electrocution to personnel. It is important to always check the integrity of insulation to ensure the safety and reliability.

Breaking Down a Cable Fault with Capacitive Discharge (“Thumping”)

POSTED BY Protec Tech Team

The capacitor discharge technique is performed with a surge generator, nicknamed “thumper.”  This device converts line power into high voltage, unidirectional, impulses that are transmitted into a faulted power cable. A simplified circuit of a surge generator connected to a faulted cable is shown in Figure 1.

Figure 1.
