SYNCHRONOUS GENERATORS SERIES EG
Electric generators are designed for prolonged operation in assembly of diesel and petrol electric machines being used as stationary, mobile, reserve and emergency source of electric power. Generators series EG is two or four-pole brushless synchronous generators with separeteexcitation from separate compact exciter of heightened frequency installed in the end bracket of generator.
Automatic voltage regulator maintains the output voltage within ±0,5%.
Generators are fully equipped for reliable operation under hard climatic conditions, i.e. they have durable tropic-resistant isolation of class H, drop-protection casing of protection grade 1P22.
Modern materials and components are used for manufacturing of generators, they have strong construction with brushless system of excitation. The special advantage of generators series EG is high power-to- mass unit ratio. Maintenance during operation is minimal.
Lower weight and overall dimensions as well as availability of modification with back arrangement of terminal box (see picture) make generators EG especially convenient to use in limited space, e.g. in mobile repair workshops.
Generators series EG may be delivered in two versions: with single bearing and two bearings to meet connection requirements of driving engine.
Construction design by way of mounting is SAE. On request different constructions are also available: to suit for assembly with any driving engine; generators suitable to mount at mobile repair workshops (with back arrangement of terminal box) as well as single-phase.
On request generators may be delivered with controllers for parallel operation
On request of the customer together with the generator for mobile rapair workshops can be supplied hinged control panels of EG 202 series electric generators.
In the configuration of the control panel, at the request of the customer may include the following electrical appliances:
- circuit breaker for overcurrent protection,
- automatic switch for connecting and disconnecting the generator from the network,
- ammeter 1 pc. or 3 pcs. (on request),
- voltmeter 1 pcs. or 3 pcs. (on request),
- frequency meter for measuring the frequency of the current,
- hour meter for accounting of the spent resource ,
- three-phase and single-phase sockets and plugs for conneection of electrical equipment and electrical appliances,
- signal lights for voltage warring.
All components are mounted in a metal box. Degree of protecnion IP 23.
