Acceptance Testing
+ -

All electrical systems and equipment must pass acceptance tests prior to
final acceptance by the end user. These tests are in addition to acceptance tests specified by equipment manufacturers. Acceptance testing must be performed by an independent third party.

Maintenance Testing
+ -

Safety first, foremost, and always. Maintenance means periodic inspections, repairs, and replacement as necessary. Maintenance is a systematic series of preventative measures to ensure the safety of all personnel working around the equipment, and the quality of the equipment itself.

Arc Flash Hazard Analysis
+ -

Arc flashes are an electrical explosion that results from a short circuit that ionizes the air between conductors. This occurs from tools, panels or other conductive items that might accidentally contact the conductors. This most often happens because of human error and is preventable in most cases.

UPS & Battery Services
+ -

ESR Electrical Services is a Toshiba authorized representative and we offer all of the uninterrupted power supply services available as well as battery and DC system support.

Electrical Commissioning
+ -

Commissioning is the systematic process where a piece of equipment, system, or facility is tested to verify that it functions in accordance with the design intent and owner’s operational requirements. Level 1-5 electrical commissioning is essential to the startup of any electrical system for the first time, regardless of size or industry. After electrical equipment is installed, ESR Electrical Services will perform visual, mechanical, and electrical tests to help ensure trouble-free energizing of the equipment.
