Substation Journeymen are on call 24 hours a day, 365 days a year, for any emergency power distribution services. For regularly scheduled maintenance, we provide a summary of your equipment, and observations outlining your current conditions and proposed courses of action.
Depending on the size of the substation and types of equipment, you may wish to expand the basic program to meet your individual requirements. We follow the IHSA safe work practices guidelines, the C.E.C and Ontario Electrical Safety Code rules and regulations.
We supply a full range of construction, maintenance, testing and emergency services regarding your High Voltage power systems.
Our procedures are consistent with Utility Pre-Service Inspection and Insurance Company Loss of Use coverage requirements.
We can advise on the requirements for and the installation of all your High Voltage equipment needs. For example, our list of Standard Modular Substation components is as follows:
- Steel or aluminum structure, lattice construction or free standing, terminal pole
- Incoming phase strain insulators
- Main isolating switch. Load break or air break
- Aluminum tubular buswork complete with connectors
- Bus support insulators and clamps
- Surge (lightning) arresters, intermediate class, distribution or station
- Power fuses, mounts, holders and refills complete
- Flexible cable drops to transformers
- Structure and transformer foundations
- Transformer, tamper proof or TLO
- Switch operating linkage, handle, interlocks, and connectors
- Gradient control mat
- Equipment grounding conductors/connectors
- Fuse caution sign
- Fence and grounding cables/connectors
- Ground rod, connectors and inspection box
- Fence enclosure
- Danger signs
Protection, Co-ordination, Short Circuit, Arc Flash
We offer technical services related to the protection and control of your high voltage system up to and including your main low voltage service entrance equipment. This service includes co-ordination studies field testing of many different breakers and relays. Also complete short circuit and arc flash studies. Infrared, Ultra Sonic and Partial Discharge testing.
Underground Cable Installations and Locating
We offer installation of cable ductbanks, cable installation and termination. We also provide field acceptance testing, ie. Hi Pot (High Potential D.C.) testing and Time Domain Reflectometer testing of high voltage cable installations. We offer underground cable location services using the latest available technology.
We offer supply and installation of Co-Generation projects including viability analysis, material acquisition, installation, operation and continuing maintenance programs.
