Ratings definition (According to standard ISO8528 1:2005) PRP - Prime Power: It is defined as being the maximum power which a generating set is capable of delivering continuously whilst supplying a variable electrical load when operated for an unlimited number of hours per year under the agreed operating conditions with the maintenance intervals and procedures being carried out as prescribed by the manufacturer. The permissible average power output over 24 h of operation shall not exceed 70 % of the prime power. LTP - Limited-Time running Power: It is defined as the maximum power available, under the agreed operating conditions, for which the generating set is capable of delivering for up to 500 h of operation per year (whose no more than 300 for continuative use) with the maintenance intervals and procedures being carried out as prescribed by the manufacturers. No overload capability is available.

Alternator Specifications

Alternator: Linz

Model: E1S13MD

Voltage V: 400

Frequency Hz: 50

Power factor cos Ï•: 0.8

Type: Brushes

Poles: 4

Voltage regulation system: Compound

Voltage tolerance % 4 Efficiency @ 75% load %: 85.4

Class: H

IP protection: 21

The E1S/4 series includes three-phase 4 poles alternators with brushes and compound regulation. Mechanical structure Robust mechanical structure which permits easy access to the connections and components during routine maintenance check-ups. Voltage accuracy: ± 4% from no load to full load, cosÏ• = 0.8 at constant rotation speed. Output voltage wave form: The low harmonic content (<5%) allows supplying any type of load, including distorting loads. Short circuit current: In case of short circuit the permanent current exceeds rated current by three times, ensuring the correct operation of protections. Overload: 10% overload for one hour every 6 hours is normally accepted. Short overloads can be very high (three times the rated current). Asynchronous motors starting: 1 HP per KVA of the generator can be started.
