Initial Inspection and Diagnostic Testing

Technicians begin by visually inspecting the generator enclosure, mounting, and electrical connections. Using digital multimeters, infrared cameras, and vibration analyzers, they assess system health while the generator runs under both no-load and load conditions. Diagnostic codes from the control panel are downloaded for deeper analysis, revealing hidden trends such as declining oil pressure or rising harmonic distortion.

Fuel System Optimization

Fuel quality exerts a major influence on generator reliability. HEP measures fuel pressure, cleans supply lines, and replaces aging filters. For diesel sets, technicians sample tank fuel to check for water contamination or microbial growth. When needed, fuel polishing services remove sludge and restore fuel compliance with ASTM standards. Correcting these issues prevents injector fouling and uneven combustion that can shorten engine life.

Electrical Output Calibration

Voltage, frequency, and phase balance require tight tolerance to protect connected loads. HEP calibrates regulators and adjusts governor settings to maintain 60 Hz output within ±2 % and voltage within specified limits. Harmonic distortion is analyzed with a power quality analyzer; corrective adjustments or component upgrades follow when distortion exceeds recommended thresholds.

Load Bank Testing for Collegedale Conditions

Running a generator under artificial load verifies performance more thoroughly than simple no-load runs. HEP deploys portable load banks sized to each unit’s capacity, progressively applying load to evaluate response, temperature stability, and fuel usage.
