ECOMAX - Power Electrical Equipment

The way this equipment is connected to the electrical network often requires the use of specialized devices. Power equipment for the most part has a high cost, and the downtime in their work negatively affects the production process and brings numerous losses. In some cases, the downtime of this equipment poses a risk to human lives. For this reason, specialized devices for connecting power electrical installations provide:

• safe mode of operation and limitation of equipment operation in dangerous modes for it;
• convenience of connecting the equipment to the mains;
• control of the parameters of the electrical network supplying power equipment;
• control of switching devices, automation and relay protection devices;
• commercial and technical metering of electrical energy.

In each individual case, a certain configuration of the power supply cabinet, control and protection of power equipment is used. It depends on the power, type and other parameters of the equipment.

One of the characteristic features of almost any power equipment is the increased starting current. This is due to the design features of electrical machines, which constitute the bulk of all low voltage power equipment. In this case, the correct adjustment of the starting protective devices, which should not react to this operating mode, is of particular importance. In addition, protective devices provide reliable protection against the following emergency modes of operation:

• overcurrent;
• underestimated voltage value;
• earth fault;
• short phase to phase;
• violation of the sequence of rotation of the phases.
