ES2M-TP Application Field and Working Principle

ES2M-TP is a hand-held, heavy-duty single-phase AC socket tester, which is widely used in the field of electrician and electrical system maintenance.

It adopts the latest technical design and excellent workmanship. It can automatically detect problems such as single-phaseground, under-voltage, over-voltage, load, circuit break and so on.

The working principle of ES2M-TP is a combination of a diode bridge and a battery.

Rectifier Diode

A rectifier diode is an electronic device with two terminal, an anode and a cathode. It converts AC electrical energy into DC electrical energy.

In the ES2M-TP, the rectifier diodes are used to convert the AC current into DC current. The current from the AC power source is sent to the diode bridge. The anode is connected to the positive pole of the diode bridge and the cathode is connected to the negative pole of the diode bridge. The diodes are placed in such a way that each anode has two cathodes directly in front of it, forming two partially separate circuits. The two sets of diodes are placed in such a way that the diodes linked to the anodes form two alternating current cycles.

Battery

The battery is the power source of the ES2M-TP. It is a rechargeable battery with a capacity of around 20Ah. The battery provides the necessary power to drive the rectifier diodes and to monitor the status of the AC power source.

Circuit arrangement

The ES2M-TP utilizes a reliable and robust circuit arrangement for testing. A low current is applied to the AC power source through the rectifier diodes, and a high current is applied to the AC power source through the battery. These two circuits interact to test the AC power source in different ways.

The low current circuit allows the ES2M-TP to detect system voltages, single-phase grounds, load faults and circuit breaks. It also provides input into the current-sensing circuit, which is used to detect system overloading and over-voltage.

The high current circuit provides input into the testing circuit, which is used to detect system under-voltage and open circuits.

The ES2M-TP is a reliable and robust testing and maintenance tool for electricians and electrical system maintenance. It provides the necessary tools to detect and diagnose AC power source faults quickly and reliably.
